1. Description

MQ-E2-O2-Ф32 Oxygen sensor is a galvanic battery type sensor, which uses the reduction reaction of oxygen on the working electrode and the corresponding oxidation reaction of the cathode material to generate current. The magnitude of the current is proportional to the concentration of oxygen. The oxygen concentration can be determined by testing the magnitude of the current.
