MQ-5 Methane LPG Liquid Propane Gas Sensor Module

This MQ-5 Methane LPG Liquid Propane Gas Sensor Module is widely used in gas leakage detecting pieces of equipment in family and industry, are suitable for detecting of LPG, natural gas, town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke. The MQ5 ( MQ-5 ) is used in gas leakage detecting equipment in consumer and industry applications, this sensor is suitable for detecting LPG, natural gas, coal gas. Avoid the noise of alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to the corresponding 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 Connections VCC ↔ 2.5V ~ 5.0V GND ↔ ground Aout ↔ MCU.IO (analog output) Dout ↔ MCU.IO (digital output) Features : High sensitivity to LPG, natural gas, town gas. Small sensitivity to alcohol, smoke. Simple drive circuit. Indication of the signal output Dual signal output (analog output, and TTL level output) TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller) 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage Liquefied petroleum gas, natural gas, city gas, better sensitivity Has a long life and reliable stability Fast response and recovery characteristics Specifications: Model: MQ-5 Operating Voltage(VDC): 5 Operating Temperature (°C): -20 to 40 Length (mm): 32 Width (mm): 20 Height (mm): 22 Weight (gm): 7 Applications : Liquefied petroleum gas, natural gas, coal gas monitoring device suitable for home or industrial. Excellent resistance to alcohol, smoke interference ability Package Includes : 1 x MQ-5 Methane LPG Liquid Propane Gas Sensor Module
