Description

Features
Size: 32 x 20 x 22mm / 1.25 x 0.78 x 0.86"
The main chip: MQ-4 gas sensing probe
Operating voltage: DC 5V
Power (current): 150mA
DO Output: 0.1V/5V
AO Output: 0.1~0.3V
Indication of the signal output
Dual signal output (analog output, and TTL level output)
TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
Has better sensitivity for natural gas.
