1. What is the difference between semiconductor sensors and electrochemical sensors?
Answer: There is no good linear correspondence between gas concentration and voltage in semiconductor sensors, and they are generally only used for products with fixed-point calibration; Electrochemical sensors have a good linear correspondence between gas concentration and output current, making them suitable for quantitative detection products.
2.Is the power consumption of electrochemical sensors high?
Answer: The principle of an electrochemical sensor is that the gas being measured undergoes an oxidation-reduction reaction on the electrode surface under the action of a catalyst, generating an electric current. The sensor itself does not consume electricity, and after being developed into a module, other components on the module consume electricity.
