PMS7003T Dust Sensor

The PMS7003T is a 3-in-1 digital sensor module that combines a laser particle counter, temperature, and humidity sensor into one compact device. It provides accurate real-time measurement of PM1.0, PM2.5, and PM10 concentrations along with ambient temperature and relative humidity.

Using laser scattering technology, it ensures stable performance, fast response, and long service life. The UART digital interface makes integration easy with microcontrollers, Raspberry Pi, and other IoT platforms, making it ideal for air purifiers, smart homes, HVAC systems, and environmental monitoring.
