yle="color:#282828;margin-bottom:0.0px;margin-top:0.0px;"> Product Details The gas-sensing material used in the MQ-8 hydrogen gas sensor is tin oxide (SnO2) with a low conductivity in clean air. whenIn the presence of hydrogen gas in the environment, the conductivity of the sensor increases as the concentration of combustible gases in the air increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit. MQ-8 hydrogenThe sensitivity to hydrogen is high and the monitoring of other hydrogen-containing gases is also ideal. This sensor can detect a variety of hydrogen-containing gas, especially the city gas, is a suitable for a variety of low-cost applicationsThe Sensor characteristics In a wide range of concentrations of hydrogen has a good sensitivity Long life, low cost Simple drive circuit can be main application Household gas leak alarm Industrial combustible gas alarm Portable gas detector Technical indicators Product number | MQ-8 hydrogen sensor | product type | Semiconductor gas sensor | Standard package | Bakelite | Detection of gas | hydrogen | Detection of concentration | 100-1000ppm (hydrogen) | Standard circuit conditions | Circuit voltage | VC | ≤24V DC | Heating voltage | VH | 5.0V ± 0.2V ACorDC | Load Resistance | RL | Adjustable | Characteristics of Gas Sensors under Standard Test Conditions | Heating resistance | RH | 31Ω ± 3Ω (room temperature) | Heating power consumption | PH | ≤900mW | Sensitive body surface resistance | RS | 2KΩ-20KΩ (in 1000ppm H2) | Sensitivity | S | Rs (in air) / Rs (1000 ppm hydrogen) ≥5 | Concentration slope | Α | ≤0.6 (R5000ppm/ R3000ppmCH4) | Standard test conditions | temperature humidity | 20 ° C ± 2 ° C; 65% ± 5% RH | Standard test circuit | Vc: 5.0V ± 0.1V; VH: 5.0V ± 0.1V | Warm up time | Not less than 48 hours |
