Principle Introduction:
This ZC02 gas sensor Module adopts high-stability catalytic gas sensor, high-performance micro-computer processor, and infrared remote adjustment mode, which makes the module with high reliability and simple debugging. Besides, this module have sensor breakdown warning and zero calibration limit functions, avoiding module continuous alarm or no alarm because of the broken sensor. When the methane concentration in air gets higher than the alarm point, it will control the mining lamp to flicker, to remind the workers to ventilate or evacuate timely. When the methane concentration declines to normal point, this gas sensor module will control the mining light recovery the normal lighting status, so that the personnel and property safety is assured and unnecessary loss is avoided.

Applications :
Methane alarm mine lamp, industrial flammable gas leakage detector
