20200911· MQ4 Methane Sensor Overview. At the heart of the MQ4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.

20161018· The MQ4 Methane Gas Sensor detects the concentration of methane gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 200 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V.

Gas Sensor Specification: Voltage : 5V DC DO Output : /5V AO Output : Compatible : Arduino / Raspberry Pi

20181002· The connections of MQ4 Gas Sensor Module are very simple. They are made as follows: VCC to 5V; GND to GND; AO to AnalogO; DO to DigitalO; Using a MQ sensor and detecting the gas is quite easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is …

The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. 10 in stock. MQ4 Methane Natural Gas Sensor quantity . Add to cart ...

Gas Sensor MQ4 is a simpletouse compressed natural gas (CNG) sensor, suitable for sensing natural gas concentrations in the air.

The gas sensing layer on the sensor unit is made of tin dioxide (SnO2), which has lower conductivity in clean air. The conductivity increases as the levels of methane rise. The detection range of the sensor is 20010000ppm of methane. To calibrate the sensor for the environment you’ll be using it in, Methane click has a small potentiometer that allows you to adjust the load resistance of the ...
