Size: 35 mm X wide 22 mm
The main chip: LM393, MQ-5 gas sensor
Working voltage: dc 5 v
Has the signal output instructions.
Double road signal output (simulated output and TTL level output)
TTL output effective signal for low level. (when output low electricity at ordinary times, can be directly light signal by SCM)
Analog output 0 ~ 5 V voltage, the higher concentration the higher the voltage.
They are used in gas leakage detecting equipments in family and industry, are suitable for detecting of LPG, natural gas , town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke.
Has long use life and reliable stability
Fast response characteristics of recovery
