Homemade Particle Powered Indoor Air Quality Sensor

20190402· The HPMA115. The particle sensor is a bit more tricky. When it is turned on, the device starts sending particulate data on a regular interval. it’s in autosend mode every time it powers up. I tried previously to configure the device but sometimes I wouldn’t get a response back. It was always hit and miss. It drove me crazy. So, in order to turn the device off wen you’re not using ...

I need help getting sensors to work properly Programming ...

20210629· Hi. I''m not completely new to Arduino, but far from an expert. I have a sensor board that is supposed to be compatible with the Adafruit feather boards. The maker wrote all the libraries to work with Particle Workbench, but I''m using Arduino IDE and the examples won''t compile properly. So, I started by going through examples in Arduino. There are 3 sensors. A CCS811, a Si7021, and a HPMA115S0 ...

AirQualityWing issues with Particle Argon and Xenon ...

Yes, the HPMA115 is plugged in. Incidentally, shouldn’t the CCS811 have a plastic cover/case? Also please send pictures of the top bottom of the AQW. There should be a small cut in a trace going to the CCS811 on the bottom side. This could affect the CCS811 I2C operations but it shouldn’t affect the Si7021. jaredwolff. otherguy looks like this board was damaged. Unfortunately I’m not ...

Air Quality Wing Documentation Jared Wolff

20191113· That way the HPMA115 get’s a clean 5V no matter what it’s connected to. The power supply is only designed to supply the HPMA115. The Si7021 is situated on a lily pad. If you look closely there is no ground fill on either side. This helps isolate the heater inside from other heat sources on the board. (Primarily the CCS811!) That way you get accurate readings using the standard factory ...
