Detailed introduction of particle detector OPC-N3 (PM2.5 sensor/dust sensor):
OPC-N3 is an upgraded third-generation product based on OPC-N1 and OPC-N2. With the same exterior dimensions as OPC-N2, the range has increased to 0.38-40um, and the number of channels has increased from 16 to 24. At the same time, onboard temperature and humidity sensors have been added to reduce standby mode power consumption and detect PM1, PM2.5, and PM10.
