Mikroe Alcohol Click (Mikroe-1586) – MQ-3 Alcohol Gas Sensor Board, Analog Output, Range: 0.04~4mg/l
The Mikroe Alcohol Click (Mikroe-1586) is a MikroBUS-compatible gas sensor board featuring the MQ-3 semiconductor sensor, designed for detecting alcohol vapor concentrations from 0.04 to 4 mg/l. It provides an analog output signal for easy interfacing with target microcontrollers like STM32, PIC, and Arduino via the mikroBUS standard.
Features
- High-sensitivity MQ-3 semiconductor alcohol gas sensor with SnO2 sensing layer.
- Detects alcohol vapor concentrations from 0.04 mg/l to 4 mg/l.
- Analog voltage output for direct ADC connection to microcontrollers.
- MikroBUS standard interface ensures plug-and-play compatibility with a wide range of development boards.
- On-board potentiometer for calibrating sensor load resistance to the operating environment.

The Mikroe Alcohol Click utilizes an MQ-3 gas sensor, which employs a tin dioxide (SnO2) semiconductor sensing layer. In clean air, the conductivity of this layer is low. When alcohol vapor is present, the conductivity increases proportionally to the gas concentration, generating a corresponding analog voltage signal on the AN pin.
Designed for 5V operation and compatible with the mikroBUS socket standard, this Click board simplifies integration into embedded systems for gas monitoring. The included potentiometer allows for precise adjustment of the sensor’s load resistance, enabling calibration for optimal sensitivity and stability in specific application environments.
