Description:
The MQ-6 Liquefied Petroleum Gas (LPG), Isobutane, and Propane Gas Sensor Module is a reliable and affordable solution for adding gas detection capabilities to your projects. Designed for sensing LPG, propane, and butane concentrations in the air, the MQ-6 sensor can detect gas concentrations anywhere from 200 to 10,000 ppm. Its high sensitivity and fast response time make it ideal for use in gas leakage detection systems, industrial applications, and portable gas detectors.

The MQ-6 sensor uses tin oxide (SnO2) as a sensitive material, which has low conductivity in clean air. When combustible gases like LPG, propane, or butane are present, the sensor’s conductivity increases in proportion to the concentration of the gas. This change in conductivity is converted into an analog output signal that corresponds to the gas concentration, and the detection range can be adjusted using the onboard potentiometer.

Features:

• Wide Gas Detection Range: Detects LPG, butane, propane, and other combustible gases from 200 to 10,000 ppm.

• Dual Signal Outputs: Provides both analog output (0 ~ 5V) and TTL level output, which can be directly interfaced with microcontrollers.

• Adjustable Sensitivity: Use the potentiometer to adjust the sensor’s detection range and sensitivity.

• Fast Response: High sensitivity and quick recovery make it ideal for fast gas detection.

• Cost-Effective and Reliable: Offers long life, reliable stability, and low cost for various applications.

• Easy to Use: The simple circuit requires 5V power, a load resistance, and output to an ADC for accurate readings.
