PMS 22 particle counter is a sensor module that uses the principle of laser scattering to detect 0.3μm, 0.5μm, 1μm, 2.5μm, 5μm, 10μm in the atmospheric environment. The sensor is made with advanced processing chips and light-sensitive elements. After collected, the signals are processed by a microprocessor and output in the form of a universal digital interface.
The PMS 22 can accurately detect the counts of different sizes of particles in the atmospheric environment in real-time.
