Trying Out a Particulate Matter Sensor

The Lab is currently working on a new project that involves environment monitoring. The device will be built around a particulate matter sensor – PMS5003. It will be driven most likely by a Sparkfun SAMD21 Mini and will use Adafruit ST7735 TFT as a display. All those components have been tested today with a help from a little candle. The candle provided sample particulate matter and boy did it deliver…

Note, the acceptable amount of particulate matter in air is approximately 25 µg/m3.
