Toxic Gas Sensor
Application:
Widely used in commercial, especially civil fields, for hydrogen concentration detectionProduct characteristics:
Low power consumptionDescription
MQ-E2-H2 hydrogen sensor is a fuel cell type sensor. Hydrogen and oxygen undergo corresponding oxidation-reduction 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 hydrogen concentration and follows Faraday's law. The hydrogen concentration can be determined by measuring the magnitude of the current.
