The PMS5003S Sensor Modules ROHS manufactured by Plantower is a miniaturized digital Particulate Matter (PM) sensor that can be used to measure PM1.0, PM2.5 and PM10 in the environment. It is equipped with a high-precision laser particle sensor combined with a multi-channeled detector which can detect particles of different sizes separately; the detection range for PM1.0, PM2.5 and PM10 is 0.3~1.0um, 0.6~2.5um and 1.0~10um respectively. It also has a fan which measures the amount of particles. The PMS5003S is capable of accurate and stable particle measuring as it has a high sensitivity level and the fan operates at a low noise level. This feature allows it to be used in a variety of applications such as industrial dust monitoring, air purifier control, environmental monitoring and more. The PMS5003S is RoHS compliant, making it an ideal and safe option for various industries.
