Specification:
- The gas sensing material used in the MQ-4 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:
1. It adopts high quality double panel design with power indication and TTL signal output indication;
2. It has DO switch signal (TTL) output and AO analog signal output;
3. 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)
4. The voltage of the analog output, the higher the concentration, the higher the voltage.
5. It has good sensitivity to gas and natural gas detection.
6. there are four screw holes for easy positioning;
7. product dimensions: 32 (L) * 20 (W) * 22 (H)
8. has a long service life and reliable stability
9. fast response recovery characteristics
Electrical Performance:

Dection of gas: Natural gas/Methane
Dection of Concentration:300-10000ppm
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 non-polluting), the highest concentration voltage is about 4V
Using the chip: AT89S52
Crystal: 11.0592MHZ
Baud rate: 9600
Compilation environment: Keil
Special Reminder:
After the sensor is energized, it needs to be preheated for about 20S, and the measured data is stable. The heating of the sensor is a normal phenomenon, because there is a heating wire inside, if it is hot, it is not normal.
Package Included:
1 x MQ-4 Gas Sensor Module
