Product Description

Methane CH4 Sensor Semiconductor Gas Sensor for Natural Gas MQ-K4


Specification:

Sensitive material of MQ-Q4 gas sensor isSnO2, which with lower conductivity in clean air. When the targetcombustible gas exist, the sensor’s conductivity is higher along with the gasconcentration rising. Please use simple electronic circuit, Convert change ofconductivity to correspond output signal of gas concentration. MQ-K4 gassensor has high sensitivity to Methane, also to Propane and Butane. The sensorcould be used to detect different combustible gas, especially Methane; it iswith low cost and suitable for different application.


Character:

1. Good sensitivity to Combustible gas in widerange

2. High sensitivity to Natural gas

3. Long life and low cost

4. Simple drive circuit


Application:

1. Domestic gas leakage detector

2. Industrial Combustible gas detector

3. Portable gas detector
