what is the difference between Semiconductor and infrared?
A: The working principle of infrared is through the module infrared lights emit infrared light waves, and the receiving time of the receiver at the other end is used to determine the co2 concentration., very accurate, the infrared working principle is used in industrial CO2 gas measuring equipment. In addition, the working principle of semiconductor is to determine co2 concentration by sensing the content of irritant gas in the air by sensors. The advantage of semiconductor is fast test response and low overall cost, the disadvantage is that it will be disturbed by other gases, resulting in a larger error in test results than infrared ones. Infrared sensors have no disadvantages.
