Arduino or Raspberry Pi? Pros and cons in IoT use.

Some people consider the Arduino platform to be the best for beginners, however, the novice will handle both Arduino and Raspberry Pi board. The choice between platforms should mainly depend on the characteristics of the project.

The origin of both platfoms

The founder of Arduino is Massimo Banzi, a lecturer at the now-defunct Italian Interaction Design Institute Ivrea, who developed a microcontroller in cooperation with students from this university. The Arduino programming language, based on the Wiring environment and basically on the C/C++ language, was designed by Hernando Barragán, a student of Banzi. The site prepared by Hernando Barragán presents exactly all the work on the project, which clearly shows that this success has more than one father.

In the case of Rasberry Pi, the project also had its source at the university. More specifically, at the University of Cambridge. Three lecturers: Jack Lang, Alan Mycroft and Robert Mullins came up with the idea of ​​developing a simple and above all cheap computer for learning programming. The first prototypes were created between 2006 and 2008. In the next step, seeing the potential of their solution, the men established cooperation with Pete Lamas, an integrated circuit designer at BroadCom, and David Braben, one of the developers of the Elite game, and together they founded the Raspberry Pi Foundation.

As a result, both platforms, which were originally intended to be used for learning by students, due to their low price and simplicity of use, became extremely popular among amateur users of consumer electronics and control, and appeared in mass sales.

So what should you choose – Arduino or Raspberry Pi?

The answer is basically simple – Arduino is ideal for simpler projects. Raspberry Pi will be useful for solutions that require more computing power. Arduino has only 2 kilobytes of RAM. Raspberry Pi has a RAM size of 1 GB. So Arduino is a simple microcontroller, meanwhile Raspberry is actually a small computer. Not without significance is the fact that the Arduino IDE is easier to use than Linux. So if you need a simple control of watering your garden, Arduino will work perfectly. Several sensors and a few lines of code will do the trick. For Raspberry Pi, to achieve the same effect, you will first need to install the system and the necessary libraries. There will be a lot more work and the effect will be the same – watering the garden at a specific time.

So choose Arduino when you need to use a simple solution for frequently repeated activities, e.g. controlling the watering of the garden, switching on and off the external lighting at a specific time, opening the gate, etc. However, because Raspberry can run many tasks at the same time, it is a computer, work simultaneously as a home printer server and operate the monitoring system. Home weather stations are popular and Raspberry will be perfect for this application because of the need to collect information from several sensors (temperature, wind strength, humidity). Raspberry Pi will therefore be a good choice for anyone interested in IoT, i.e. the Internet of Things at home. Examples of ready projects can be found here: https://modberry.techbase.eu/

Why not both?

Nothing prevents you from starting with Arduino and continuing with Raspberry Pi. By using Arduino or ESP32-based solutions you will learn the basics and you will get the effect quickly and relatively easily. But only Rasbperry Pi will allow you to make much more difficult projects. And both platforms can be combined with each other. Arduino/ESP32 can be used to read information from sensors and control e.g. motors (for example a garage door). Raspberry Pi will control all devices and send the collected data, e.g. to a mobile phone. You can do more together.

When the news came out that ventilator shortages could be a problem, many saw the need for alternatives to the big manufacturers and rushed to create them. Unlike industrial projects, these projects were open and shared. Currently, Robert Reed and his group are starting to systematically evaluate the ranking of over 80 such open source projects.

Their work is a milestone in public research and development efforts to solve problems. For many ventilator builders, the group recognized the need for independent evaluation and testing of various projects. This control provides important feedback to both designers and future builders. This is a service you can expect from government regulators if they can act very quickly.

Reid and colleagues Geoff Mulligan, Lauria Clarke, Juan E. Villacres Perez and Avinash Baskaran to help to learn about these studies. This includes submission of modular team designs that allow distributed production and unique suggestions for testing and monitoring these systems. This is called VentMon.

Industrial Arduino-like devices as a base of medical equipment?

When industrial IoT devices and edge devices, like medical equipment work together, digital information becomes more powerful. Especially in contexts where you need to collect data in a traditional edge context, or control the servo-motors of a ventilatr. You can then remotely monitor the container using the sensor.

By introducing AI (artificial intelligence) into the device itself, edge computing can also make more context-sensitive, quick decisions at the edge. Data gathered from the sensors can be transferred to the cloud at any time after local work has been completed, contributing to a more global AI process, or archived. With the combination of industrial IoT devices and advanced technology, high quality analysis and small footprint will become the AI standard in 2020.

One of the main problems during the COVID-19 crisis is the lack of adequate ventilator support for patients, a key component of equipment that has a major impact on the breathing of critically ill patients. It’s clear that more ventilators are needed because there aren’t enough devices currently in the hospital for all potential patients who can get infected. Developers use existing creation tools to participate in service calls, for example trying to create a cheap open source Arduino-based ventilators.

Another solution is the AgVa phone ventilator produced by the Indian based company AgVa Healthcare which used one tool we already have: smartphone. The AgVa Phone Ventilator, known officially as the AgVa Advance Pure, is a portable and mobile ventilator system that does the work of a typical ventilator. The vision around the ventilator is that patients should not always have to be stuck to the hospitals all the time.

The primary focus of the ventilator is to provide mechanical ventilation for everyone in need. Its small package ensures easy storage and transportation, whereas its intuitive user interface makes it extremely easy to use even for a non trained person. Finally due to its phenomenally low cost and no need for infrastructure requirement makes it ideal for scaling up the ICU.

Battery powered IoT devices crucial to 2020+ standards

Technology must transfer data to the central system in real time, otherwise it may have negative consequences. If the sensor battery power runs out, a machine failure may stop production for one day or lead to direct danger. If battery life is unbelievable and short, IoT applications will become useless, causing more interference rather than making life easier for its intended purpose. Therefore battery powered IoT devices come as a standard in up-to-date IoT installations

Wireless sensors and sensor networks are one of the elements of the Internet of Things systems and intelligent factories. Replacing the standard sensors and data collection devices with versions that communicate wirelessly gives many benefits, but also enforces a highly thought-out system design that will minimize energy consumption. This is important because these systems must work for many years without servicing. In the article we present the issues regarding the design of systems and forecasting of energy consumption in IoT systems.

Wireless communication vs Battery power

The idea of wireless sensor networks has been around for at least two decades, while the IEEE subgroup working on personal wireless networks defined the 802.15.4 standard in 2003, a year later the first versions of ZigBee appeared. Since then, many varieties of wireless communication have been developed, such as LoRa & NarrowBand-IoT and additional functions introduced, as a result of which designers now have a choice of various open or proprietary protocols. What significantly affects the way the entire project is implemented is energy consumption.

The basic elements of these systems are sensors that measure physical quantities. Some signal and data processing capabilities are also important. After all, the communication interface is important, which will allow you to pass the measured data on. Such a sensor node should wake up from time to time, make contact with its superordinate controller, transfer data and fall back to sleep again. Battery life depends on the total charge collected. Minimizing this consumption in the long run means that you need to minimize energy consumption during each work cycle. In many cases, the sensor will only work for a small fraction of the time. A measurement that lasts a few milliseconds can be triggered once per second, once per minute, or even less frequently. Therefore, the energy consumed in sleep mode may dominate the total energy consumption.

Battery powered sensors market growth

The lifetime of IoT sensors varies greatly: some last a year years, others 10, the first being the most realistic. When organizations need to deploy engineers to install new batteries in sensors and employ staff to monitor them, the benefits of technology itself are beginning to run out.

Battery powered IoT devices crucial to 2020+ standards

It is estimated that in 2020 nearly 31 billion devices will be connected to the Internet of Things. Such forecasts provide ample opportunities, especially for producers associated with the products that make up it, and they are intensified by the developing IoT technology.

Battery-ready IoT devices based on ESP32

Battery / SuperCap power support allows the processes and data to be securely executed, saved or transferred, and the operating system to be safely shutdown or reboot, if the power source has been restored. The power failure alert can also be sent to cloud service, to perform custom task, specified by user or self-learning AI algorithm.

The Moduino device is a comprehensive end-point controller for variety of sensors located throughout any installation. It fully supports temperature and humidity sensors and new ones are currently developed, e.g. accelerometer, gyroscope, magnetometer, etc.

ModuinoModBerry symbiosis allows wide range of wake-up/sleep schedule customization, in order to perform best and save energy accordingly to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.

With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using schedule/timer. Another option is wake on external trigger, e.g. change of input, etc. All the options for sleep, shutdown and wake can be configured for various scenarios to ensure constant operation of devices, safety of data and continuity of work in case of power failure in any installation.

In March, sales of Raspberry Pi single-board computers totaled 640,000. The consumer find it the cheapest way to start tinkering and drove to the second-largest sales month since Raspberry Foundation began selling for home use.

Other uses of Raspberry Pi computers are more directly associated with the appearance of COVID-19. For example, in Colombia, efforts are underway to run a ventilator on a Pi computer, and if successful, it will help solve the problem of the lack of traditional ventilation equipment in this country.

I think what this is telling us is that we’re seeing genuine consumer use of the product. It’s not like your desktop PC – you’re not going to be able play Crysis on it – but if you want a machine you can use to edit documents, use the web, use Gmail and Office 365 and all the baseline use cases of a general purpose computer, the Raspberry Pi 4 is a product we’ve made to get over that bar.

Eben Upton, the Raspberry Pi’s co-creator for Techrepublic

When the Raspberry Pi Foundation asked to talk about how to deal with COVID-19 using Raspberry Pi devices, one of the most common uses he saw was 3D printing with use of Raspberry Pi, especially for 3d-printed faceshields.

Arduino-based ventilator to help coronavirus patients

A month ago we wrote about Arduino-based solution, similar to the one tested in Columbia. As far as manufacturing and using home-made medical equipment is not advised, the spread of the COVID-19 might push humanity to such solutions. Johnny Lee’s project involves a simple, low-cost ventilator controlled via Arduino.

The idea is that since these machines are basically just blowers controlled by a brushless DC motor, an Arduino Nano equipped with an electonic speed controller could allow it to act as a one. Such a setup has been shown to provide more than enough pressure for a ventilator used on COVID-19 patients. This device has in no way been evaluated or approved for medical use, but it does provide a starting point for experimentation.

The Colombian medical team tests a fan made with the Raspberry Pi and easily available parts. Robotics engineer Marco Mascolo said he made the project because he knew that machines were in great demand to handle Covid-19. The design and code was published online in March by a Californian, stating that he had ‘no previous experience creating medical devices’.

The ventilator control computer is the most important part. Raspberry Pi can set the air pressure, open and close the valves to adjust if the patient needs full or partial breath support, and Mascorro has integrated the code with open software so that anyone can use or change it for free.
