Air Monitoring Breakout

Air Monitoring breakout for Raspberry Pi, an open-source portable sensor that can provide the level of quantity of the suspended particulates with their mass. Air Monitoring breakout has a powerful and hi-tech 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 3.3 V. It communicates via UART(serial) with the standby current ≤200 Microampere(μA) of the sensor. It is compatible with Raspberry Pi, Beaglebone, Arduino, STM32, PIC, AVR, ARM, etc.
