Sensitive for LPG, propane, hydrogen. Output voltage boosts along with the concentration of the measured gases increases. Fast response and recovery. Features boost circuit. Adjustable sensitivity. Signal output indicator.


Dimension: 32 x 22 x 27mm (L x W x H)

The main chip: LM393, ZYMQ-2 gas sensor

Operating voltage: 5V DC

Dual signal output (analog output, and TTL level output)

TTL output valid signal is low level. (When the output low level signal light can be directly connected microcontroller)

Analog output: 0 ~ 5V voltage, the higher the concentration the higher the voltage.
