SDS011 dust sensor reading · GitHub

To keep a small form factor, I have connected an SDS011 directly to a Raspberry PI Zero W. This way you don''t need a clunky USB UART things and ditto USB > MicroUSB converter. It all works like a charm, but once you wake it up after putting it to sleep, it reboots the RPI. Does anyone else have any experience with this? It''s probably fixed with giving the sensor its own 5V feed I guess, but open to …

The SDS011 Air Quality Sensor experiment

Spec sheet: This is the specification for the SDS011. One should not consider all those values for granted as there is quite often a big difference between what is said to be possible and what is actually possible (and this is why we are setting up all our experiments). Output: , PM10 ; Measuring Range: μg/m3

The SDS011 Air Quality Sensor experiment

Note that the SDS011 humidity working range is 070%. This is so good, since above 70% humidity, the readings become unrealiable. Inside look at the sensor The clever engineering in the SD011 is to use the PCB as one side of the casing (allowing to reduce the BOM cost). The diode is mounted on the PCB side (this is mandatory as any noise between the doide and the LNA should be avoided). The laser …

GitHub mrtnrey/sds011: Reading a SDS011 sensor on a ...

The TLMR3020 expects the SDS011 already connected the USB port while booting. In the /root directory you''ll find the file , containing "TEST". If you would like your device sending data to Madavi, you have to replace the word "TEST" with the serial number of your TLMR3020. This has to be done manually since the TLMR3020 is ignorant on its own serial number.
