User attention ▪ When the laser particle sensor module is used outdoors, please make sure the inlet and outlet unobstructed, dust storms, snow, and willow flocs can have a significant impact on unprotected sensors. When the laser particle sensor module works, it is recommended to use a pre-filter pre or effective protective measure in the front of inlet of the dust sensor to avoid big dust and bis substance. ▪ The sampling method of both NDIR CO2 sensor and semiconductor VOC sensor is diffusion, eyelet of gas diffusion should be reserved to make sure the gas can quickly and smoothly pass through the sensor module. www.gassensor.com.cn
