Air Monitoring HAT is the latest technology in the advanced range of products of SB Components. We developed the Air Monitoring HAT, an open-source portable sensor that has the ability to provide the level of quantity of suspended particulates with their mass. Air Monitoring HAT has a powerful and hi-tech PMSA003 sensor that provides information on 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.
