MQ-4 Methane Natural Gas Sensor Module Shield Liquefied Electronic Detector Module For Arduino: Business, Industry & Science. MQ-4 Methane Natural Gas Sensor Module Shield Liquefied Electronic Detector Module For Arduino: Business, Industry & Science. 1. It adopts high quality double panel design with power i;ndication 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) . ntration, 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 . 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.. . Electrical Performance:. . Dection of gas: Natural gas/Methane. Dection of Concentration:00-10000ppm . Input voltage: DC5V. Power consumption (current): 150mA. DO output: TTL digital quantities 0 and 1 (0.1 and 5V). AO output: 0.1-0.V (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. . . .
