TuYa WiFi 9 in 1 PM2.5 PM10 HCHO TVOC CO CO2 Meter Digital Temperature Humidity Tester LCD CO2 Detector for Air Quality Monitor

Laser sensors utilize the reflection or scattering of a laser beam from an object to measure parameters such as distance, speed, shape and position of the object. Laser sensors work by emitting a laser beam, shining the laser beam onto an object, then measuring the reflected or scattered signal from the laser beam and calculating parameters such as distance, speed, shape and position of the object based on parameters such as the time difference or phase difference of the signal. Laser sensors have the advantages of high accuracy, high speed, long life and no environmental interference.

Infrared sensors utilize infrared radiation to measure parameters such as temperature, distance, and position of an object. Infrared sensors work by emitting infrared radiation, shining infrared radiation onto an object, then measuring the reflected or scattered signal of the infrared radiation, and calculating parameters such as temperature, distance, and position of the object based on parameters such as the intensity or frequency of the signal. Infrared sensors have the advantages of non-contact measurement, suitable for high-temperature objects, and are not disturbed by light.

This detector can be used to test and display PM2.5, PM10, carbonic oxide, carbon dioxide, TVOC, HCHO, and AQI at the same time. Uses high-precise Infrared/Laser sensor, with high sensitivity, superior interference resistance ability, stable working performance, with low power consumption. And also have time and date display and WiFi function. Tuya APP control, suitable for agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.
