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
A compact, versatile, and extremely accurate tool for assessing ALL types of environmental damage
A machine that consists of a face mask sanitiser (using UV LEDs), an automatic hand sanitising machine and an ARM MCU that checks vitals.
Also, yes, it will not compile on the UNO, primarily because the UNO doesn't use the same firmware or even processor as the 33 BLE Sense. Here's an example project using the SPS30 and an AVR-based Arduino board, though https://www.instructables.com/Interfacing-Sensirion-SPS-30-Particulate-Matter-Se/
You can, in that case, leave the line enabling softwareserial uncommented out, and replace line 7 with Serial instead of Serial1 for the define SP30 COMMS parameter.
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 CCFL is bad, and will break about a year in use, plus that is outdated technology, and as I mentioned before, and an extract from a website states: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.
