MQ4 ( MQ - 4 ) gas sensor has high sensitivity to Methane, also to Propane and Butane. The sensor could be used to detect different combustible gas, especially Methane, it is suitable for different applications. When the target combustible gas exists, the sensor’s conductivity is higher along with the gas concentration rising.
Specifications:
- Sensor Type Semiconductor
- Input Voltage: 5 VDC
- DO output: TTL digital 0 and 1 (0.1 and 5V)
- AO output: 0.1-0 .3 V (relative to pollution), the maximum concentration of a voltage of about 4V
- Detection Gas: Natural gas/Methane
- Detection Concentration: 200-10000ppm (Natural gas / Methane)
- Interface: 1 TTL compatible input (HSW), 1 TTL compatible output (ALR)
- Heater consumption: less than 750mw
- Operating temperature: 14 to 122 °F (-10 to 50°C)
- RH Related humidity less than 95%Rh
- O2 Oxygen concentration is 21% (standard condition) - Oxygen concentration can affect sensitivity
- Load resistance: 20KΩ
- Sensing Resistance Rs: 10KΩ- 60KΩ (1000ppm CH4)
- Preheat time: Over 24 hour
- Standard Encapsulation Bakelite, Metal cap
