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.
