Capture local air quality data with your Raspberry Pi!

This Air Monitoring HAT for the Raspberry Pi is an open-source portable sensor that has the ability to provide the level of quantity of suspended particulates with their mass.

The HAT has a powerful PMSA003 sensor that provides the information of suspended particulate matter (PM1.0, PM2.5, PM10) in the air per unit volume via digital output, with an operating voltage of 3.3V. Use the onboard 0.91″ OLED display to design your own data display from the readings and other data sources!

The board communicates via UART(serial) with the standby current 200 Microampere(A) of the sensor.

We also offer the same sensor on a breakout instead of HAT format!
