S4-VOC gas detection sensor is a constant potential electrolytic type sensor. VOC and oxygen will undergo corresponding oxidation-reduction reaction on the working electrode and the counter electrode respectively and release charge to form a current. The generated current is proportional to the TVOC concentration. The TVOC concentration can be determined by measuring the current.
