Alcohol Sensor
For the alcohol detector
Application:
Widely used in alcohol testing for traffic safety, environmental protection, automotive consumer goods, etc.Product characteristics:
Low power consumption1. Description
MQ-E2-C2H5OH-13×13 is a fuel battery type alcohol electrochemical sensor, alcohol and oxygen undergo corresponding redox reactions on the working electrode and the counter electrode and release charges to form current. The magnitude of the generated current is proportional to the alcohol concentration and follows Faraday's law. The alcohol concentration can be determined by testing the magnitude of the current.
