Description:

The MQ-3 Alcohol and Ethanol Analog Sensor Module is designed to detect alcohol vapours in the air. Utilizing a tin dioxide (SnOâ‚‚) sensitive layer, the sensor exhibits low conductivity in clean air, which increases in the presence of alcohol gases. This change in conductivity allows for the detection of alcohol concentrations ranging from 0.05 mg/L to 10 mg/L, making it suitable for applications such as breathalyzers, alcohol detectors, and safety monitoring systems.

The sensor operates with a heating voltage of 5V and provides an analog output signal that can be interfaced with microcontrollers and ADC modules for monitoring and analysis. Its compact design and high sensitivity make it an ideal choice for various alcohol detection applications.

Specifications:

  • Target Gas: Alcohol (Ethanol)
  • Detection Range: 0.05 mg/L to 10 mg/L
  • Heater Voltage: 5V ±0.1V
  • Load Resistance (RL): 200 kΩ
  • Heater Resistance (RH): 33Ω ±5% at room temperature
  • Heating Consumption: ≤750 mW
  • Operating Temperature: -10°C to 50°C
  • Operating Humidity: ≤95% RH
  • Sensitivity: Rs (in air) / Rs (0.4 mg/L alcohol) ≥ 5
  • Response Time: ≤10 seconds
  • Recovery Time: ≤30 seconds
