MQ 2 MQ2 Smoke Gas LPG Butane Hydrogen Gas Sensor Detector Module

MQ-2 MQ2 Smoke Gas LPG Butane Hydrogen Gas Sensor Detector Module

Module Application:
Can be used for home and factory gas leak monitoring device, suitable for liquefied gas, butane, propane, methane, smoke and other detection;

Module Features:
1, the use of high-quality double-panel design, with power indicator and TTL signal output instructions;
2, with DO switch signal (TTL) output and AO analog signal output;
3, TTL output valid signal is low. (When the output low signal lights, can be directly connected to the microcontroller or relay module)
4, the analog output voltage with the higher the higher the voltage the higher the voltage.
5, the liquefied petroleum gas, natural gas, city gas, smoke has a better sensitivity.
6, there are four screw holes to facilitate positioning;
7, product dimensions: 32 (L) * 20 (W) * 22 (H)
8, with long service life and reliable stability
9, fast response to recovery features

Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively no pollution), the maximum concentration of about 4V voltage
Special reminder: the sensor power, the need to preheat 20S or so, the measured data was stable, the sensor fever is a normal phenomenon, because the internal electric wire, if the hot is not normal.

Wiring:
1, VCC: then the power supply positive (5V)
2, GND: Connect the power supply negative
3, DO: TTL switch signal output
4, AO: analog signal output
