Operating Voltage: 5V DC
Indication of the signal output
Dual signal output (analog output, and TTL level output)
0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
High sensitivity to hydrogen
Can be resistant to ethanol steam, LPG (petroleum), smoke interference
Has a long life and reliable stability
Fast response and recovery characteristics
Operating Voltage is 5V
Can be used to Measure or detect LPG, Alcohol, Propane, Hydrogen, CO and even methane
Can be used as a Digital or analog sensor
The Sensitivity of Digital pin can be varied using the potentiometer
Long life and low cost
Simple drive circuit
