sensor

Before we use an instrument, it is very necessary to understand how it works, because its principle determines how it is used and some of its features. Air quality detector is a kind of instrument used to determine the quality of gas, its response speed is relatively fast, can help us know the quality of air in a certain environment in a timely manner. Since some users do not particularly understand the working principle of the air quality detector, the following is a brief introduction to you. Air quality sensor is relatively common in our daily life, it can detect formaldehyde, PM2.5, TVOC and temperature and humidity and other parameters in real time. Through the sensor on the gas concentration to play a role in detecting, can accurately measure the size of the concentration of pollutant gases, and quickly calculate the air quality index AQI, if the concentration of the current environment exceeds the standard will be immediately after the alarm.   The working principle of the a...
