    Tips: Air particle sensor basics

    ATO's air quality transmitter is an industrial-grade general-purpose particle concentration transmitter that utilizes the laser scattering measurement principle, sieves through the unique dual-frequency data acquisition technology to derive the number of particulate matter particles per unit volume of equivalent particle size, and calculates the mass concentration of particulate matter particles per unit volume of equivalent particle size with a scientifically unique algorithm.

    Uses an RS485 interface to perform the Modbus-RTU protocol through the data output via RS485 interface via Modbus-RTU protocol. It can be used in outdoor weather stations, dust monitoring, libraries, archives, industrial plants and other places where PM2.5 or PM10 concentration monitoring is required.
