Description

MQ-5 sensor introduction:
The gas-sensitive material used in the MQ-5 gas sensor is tin dioxide (SnO2), which has a lower conductivity in clean air. When the combustible gas is present in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of combustible gas in the air increases. A simple circuit can be used to convert the change in conductivity to an output signal corresponding to the gas concentration. The MQ-5 gas sensor has high sensitivity to butane, propane, and methane, and can better take care of methane and propane. This sensor can detect a variety of flammable gases, especially natural gas, and is a low-cost sensor suitable for a variety of applications.

Suitable for home or industrial monitoring devices for liquefied gas, natural gas, and gas. Excellent resistance to ethanol and smoke.
Module features:
1, using high-quality dual-panel design, with power instructions and TTL signal output instructions;
2, with a DO switch signal (TTL) output and AO analog signal output;
3, TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the MCU or relay module)
4, analog output voltage, the higher the concentration the higher the voltage.
5, have good sensitivity to gas, natural gas detection.
6, there are four screw holes for easy positioning;
Product Dimensions: 32(L)*20(W)*22(H)
8, has a long service life and reliable stability
9, rapid response recovery characteristics

Electrical performance:
Input Voltage: DC5V Power Consumption (Current): 150mA
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
AO output: 0.1-0.3V (relatively no pollution), the highest concentration voltage is about 4V
