MQ-6

MQ-6 Semiconductor Sensor for LPG Sensitive material of MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-6 gas sensor has high sensitity to Propane, Butane and LPG, also response to Natural gas. The sensor could be used to detect different combustible gas, especially Methane, it is with low cost and suitable for different application. Character * Good sensitivity to Combustible gas in wide range * High sensitivity to Propane, Butane and LPG * Long life and low cost * Simple drive circuit Application * Domestic gas leakage detector * Industrial Combustible gas detector * Portable gas detector Configuration www.DataSheet4U.com Technical Data Model No. Sensor Type Standard Encapsulation Detection Gas Concentration Loop Voltage Circuit Heater Voltage Load Resistance Heater Resistance Heater Character consumption Sensing Resistance Sensitivity Slope Vc VH RL RH PH Rs S α MQ-6 Semiconductor Bakelite (Black Bakelite) Isobutane, Butane, LPG 300-10000ppm ( Butane, Propane, LPG) ≤24V DC 5.0V±0.2V ACorDC Adjustable 31Ω±3Ω（Room Tem.） ≤900mW 2KΩ-20KΩ(in 2000ppm C3H8) Rs(in air)/Rs(1000ppm C4H10)≥5 ≤0.6( R2000ppm/R1000ppm LPG ) 20℃±2℃；65%±5%RH Vc:5.0V±0.1V； VH: 5.0V±0.1V Over 48 hours Basic test loop Vc VRL RL VH GND The above is ...
