The PM2.5 sensor adopts a laser detection method, which can accurately measure the number of dust particles per unit volume in indoor air. It outputs particulate matter mass concentration (μg/m³) through mathematical calculation and scientific calibration, and can simultaneously output PM1.0, PM2.5 and PM10 data.
The temperature and humidity measurement is implemented with a high-precision integrated temperature and humidity sensor, featuring fast response and high measurement accuracy.
A thermopile gas sensor is adopted to measure CO₂ content based on the NDIR principle. Compared with single-channel sensors or those using other measurement principles, it has the advantages of longer service life and more accurate measurement.
The high-precision electrochemical formaldehyde detection module is supplied by a world-leading electrochemical sensor provider. Including VOC, illuminance and ozone sensors, all are of the optimal performance in the industry at present.
