This reduces the circulation of air and makes the readings higher than during the day. In addition, the sweat produced during sleep, and the exhaled gas also contains a variety of VOCs, which also increases the concentration of...

The air does not circulate during storage and transportation, to achieve the best performance of the device, it needs to be placed in the outdoor ventilation for at least 6 hours before the first use. Meanwhile, each sensor has individual differences, just like everyone is with different alcohol metabolic abilities, so a small number of sensors may require longer ventilation. In this situation, to...

Laser particle sensor can obtain the number and quality of suspended particles in the air per unit volume, which is called particulate matter concentration. Meanwhile, it can output as a digital interface. Based on the principle of laser scattering, when the air outside uniformly passes through the specially designed air duct, the laser light is scattered on the suspended particles in the air, and...
