A weather monitor that measures 10 environmental properties and sends data to Blynk and over HDMI on the Vidor 4000 (HDMI is still in beta)
Project tutorial by Guntas Singh
Using the SPS30 particulate sensor with Nano 33 BLE Sense along with other sensors to build an all-purpose environmental monitor.
A machine that consists of a face mask sanitiser (using UV LEDs), an automatic hand sanitising machine and an ARM MCU that checks vitals.
Plus, I am using UV-C LEDs in my project, just in the form of small diodes, not as large tubes as the advantage is that it is easy to assemble. UVC leds are relatively cheap in my country, and they are robust and solid, are resilient to a wide range of environmental conditions, and many people can manufacture and mass produce very good ones, like Innotek. CCFL is bad, and will break about a year in use, plus that is outdated technology, and as I mentioned before, and an extract from a website states:
The CCFL is not without its drawbacks. For instance, its power consumption is relatively high, thereby generating more heat in the process. LEDs are capable of higher brightness than a CCFL.
Plus, low energy allows LEDs to be powered in the hundreds from a single Arduino which in turn can draw its power from a solar power bank, and thus is a more economic, robust, effective method of sterilization. Finally, LEDs also require much less materials to manufacture unlike CCFLs which require a lot of materials to manufacture. Along with that, you also need a separate driver and power supply, thus rendering them obsolete to LEDs. Of course, I have also included a water atomizer in the project to spray around cleaning solution or hot steam, as an additional sterilizing method.
Yes, but it’s not only for your country, you have to consider internationally as well, and in my country, Innotek UV C diodes are much better as they are more compact, smaller and are better for the environment than CCFLs, and are the only ones available. Alibaba doesn’t ship as fast to my country, and so , much better alternatives need to be considered in this pandemic. I have taken into account the universal solution for UV sterilization and that is UV LEDs.
That's a good suggestion: solar power banks would work nicely, although some workers could bring only one Windows laptop, that is an almost certainty, unless someone lives in S. Sudan or North Korea, that one PC can be used to save biodata from multiple machines, lithium-ion power banks coupled with solar panels can work :)
