What is the difference between semiconductors and infrared?

A: The working principle of infrared is that it works through the module.Infrared lights emit infrared waves, and the time it takes for the light to reach the receiver at the other end is used to determine the CO2 concentration.,The accuracy is very high.In industrial CO2 gas measurement equipment, the infrared principle is used. In addition, the working principle of semiconductors is to detect the content of irritating gases in the air to determine the concentration of CO2. The advantage of semiconductors is that the test response is fast and the overall cost is low, but the disadvantage is that it can be interfered by other gases, leading to larger testing errors than infrared sensors. Infrared sensors have no disadvantages.
