MQ-5 MQ5 Gas Detection Module MQ-5 LPG Natural Gas Coal Gas MQ5 Smoke Liquefied Flammable Methane Gas Sensor Module For Industrial And Engineering Electronics Project DIY

This MQ-5 gas detector is used for leak detection of LPG (Liquified Petroleum Gas), methane, propane, butane, natural gas and city gas, with low sensitivity to alcohol and smoke. Suitable for home and industrial use, it has fast response and recovery characteristics, long life and reliable stability.

The module features dual signal outputs: An analog output (0V to ~5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer.

• Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, convert change of conductivity to correspond output signal of gas concentration.
• MQ-5 gas sensor has high sensitivity to Methane, Propane and Butane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application.

Specification:

• The gas sensing material used in the MQ-5 gas sensor is tin dioxide (SnO2) with low conductivity in clean air.
• When there is a flammable gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of flammable gas in the air increases.
• A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.
• The MQ-4 gas sensor has high sensitivity to butane, propane and methane, and has a good balance between methane and propane.
• This sensor detects a wide range of flammable gases, especially natural gas, and is a low cost sensor for a variety of applications.
• Suitable for monitoring equipment for liquefied gases, natural gas and gas in the home or industry. Excellent resistance to ethanol and smoke.

Features:

• It adopts high quality double panel design with power indication and TTL signal output indication;
• It has DO switch signal (TTL) output and AO analog signal output;
• The 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)
• The voltage of the analog output, the higher the concentration, the higher the voltage.
• It has good sensitivity to gas and natural gas detection.
• there are four screw holes for easy positioning;
• product dimensions: 32 (L) * 20 (W) * 22 (H)
• has a long service life and reliable stability
• fast response recovery characteristics
