Toxic Gas Sensor
Application:
Widely suitable for the detection of ethylene in industrial sites and environmental protection fieldsProduct characteristics:
Low power consumptionDescription
The MQ-E3-C2H4 electrochemical gas sensor is based on the principle of electrochemistry. It uses the electrochemical reaction of the gas to be measured on the working electrode in the electrolytic cell. The current generated by the electrochemical reaction of the gas to be measured is proportional to its concentration and follows Faraday's law. Therefore, the concentration of the gas to be measured can be determined by measuring the magnitude of the reaction current.
