MQ-5 Methane Natural Gas Sensor Shield Liquefied Electronic Detector Module

MQ-5 sensor Introduction :
Sensitive material MQ-5 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-5 gas sensor of high butane , propane, methane sensitivity, methane and propane can be better taken into account. This sensor can detect a variety of combustible gases, especially natural gas , is a low-cost sensor for a variety of applications .

Suitable for home or industrial liquefied petroleum gas , natural gas, coal gas monitoring devices. Excellent resistance to alcohol, smoke interference.

Module Features :
1 , using high-quality dual-panel design, with power indicator and TTL signal output instructions;
2 , the switching signal having a DO (TTL) output and analog output AO ;
3, TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
4 , the higher the voltage , the concentration of the analog output voltage is higher.
5 , for gas, natural gas has a better detection sensitivity .
6 , there are four screw holes for easy positioning ;
7 , Product dimensions : 32 (L) * 20 (W) * 22 (H)
8 , has a long life and reliable stability
9 , rapid response and recovery characteristics

Electrical properties:
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V

Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .
