MQ-6 LPG Gas Sensor

৳ 150.00

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 & digital signal and can be read with an analog/digital input of the Arduino.

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 & digital signal and can be read with an analog/digital input of the Arduino.

This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.

1. Analog output voltage with concentration, the higher concentration, the higher voltage.
2. Has long service life and reliable stability 
3. Rapid response recovery features
Specification:
 Input voltage: DC5V 
Power consumption (current) : 150 mA 
AO output: 0.1-0.3 V (pollution-free)
Highest concentration of voltage: Approx 4 V 
Detection range of alcohol: detection range of 10 ~ 1000 PPM
Connection mode: 
 1. VCC: Positive (5 v) 
2. GND: Connect power negative 
3. DO: TTL switch signal output
4. AO: Analog signal output
