MQ-3 Alcohol Gas Sensor Module
The MQ-3 Alcohol Gas Sensor Module is user-friendly and able to detect the presence of Alcohol in the air. It features our MQ-3 sensor and offers a simplified interface for the odd pin spacing through standard 4 x 0.1? header pins.
The device offers both an analog output that reflects the gas concentration in the air and a simple-to-use digital output.
Utilize the onboard potentiometer to establish a limit for the gas concentration that will activate the digital output. Once powered with 5V, simply adjust the threshold and begin receiving readings of the surrounding gas levels. An LED indicator on the module will indicate any presence of gas. This is an ideal tool for accurately detecting alcohol levels in your breath, similar to a typical breathalyzer device.
The digital output can be easily connected to microcontrollers and other circuits, while the analog output can be attached to an ADC on a microcontroller for a variety of sensor readings.
The characteristics of MQ-3 Gas Sensor Module:
- Indication of signal output through light.
- Output of analog and level signals.
- The low TTL output signal can be directly connected to a microcontroller or relay module for convenience.
- No smoke
- This product offers both durability and dependable stability over an extended period of time.
- Features that enable a quick recovery response.
