3. Structural Drawing
The device consists of the housing, sensor part and PCB. The housing
consists of upper cover, lower cover, O-type circle and cable input hole
part. The housing function is to protect the inside part. The sensor part
consists of gas sensor, sensor protection cover, decoration part and

4.1 Position
4.1.1 For petrol gas, oil gas and alcohol gas etc. which is heavier than
the air, the position is 0.3m-0.6m higher than the ground.
4.1.2 For natural gas, CH4 etc which is lighter than the air, the position is
0.5m-2m higher than the gas source.
