MQ Series Gas Detection Module MQ-2 (ARD602)

MQ-2 Gas Sensor

Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to its high sensitivity and fast response time, a measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.

• Detector Type : ZYMQ - 2 Gas Sensor
• Detectable Concentration : 300-10000ppm (flammable gas)
• Operating Voltage: 5V DC (VCC Pin)
• Dual Signal Output (analog (AO pin) and TTL (DO pin) level output)
• TTL output signal is normally low, goes high when has is detected. Threshold is adjusted with the onboard potentiometer
• 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
• Indicator LEDs
• Power
• DO (Digital Output On)
• Dimensions (approximate) : 32mm x 20mm x 27mm LxWxH (1.25 x 0.8 x 1.1 inches)
