RS485 Smart Air Quality Testing Sensor (PM2.5 PM10)The SEN101 2005 air quality sensor is based on laser scattering technology and is primarily used to detect PM2. 5 and PM10 particle levels in the atmosphere. Equipped with a high sensitivity detection probe, it offers stable signals, high precision, a wide measurement range, and long transmission distance. This sensor is ideal for air quality monitoring in factories, schools, commercial buildings, construction sites, and other environments where air
