ZPH02(01) Dust VOC and PM2.5 Sensor PWM/UART Digital Detecting Pollution Air Pollution Dust

The sensor integrates the infrared PM2.5 detection principle and the more mature VOC detection technology, enabling simultaneous detection of PM2.5 and VOC in the same environment. The PM2.5 detection in this sensor uses the particle counting principle to sensitively detect dust particles with a diameter of 1 μm or more. The VOC sensor has extremely high sensitivity to organic volatile gases. The sensor is aged, debugged, calibrated and calibrated before leaving the factory, with good consistency and high sensitivity. With PWM, UART digital serial interface (customizable IIC interface output mode).
