Description:
The MQ3 gas sensor is part of the MQ family and is designed to detect alcohol concentration in the air. The sensing element is made of Tin Dioxide (SnO2), which has low conductivity in clean air. When the sensor comes in contact with alcohol vapors, its conductivity increases in proportion to the alcohol concentration. This sensor is ideal for measuring alcohol levels in breathalyzer applications, gas leak detection, or alcohol monitoring.

The MQ3 sensor provides both analog and digital output, which can be adjusted with an onboard potentiometer to fine-tune the sensor's sensitivity. This module is a low-cost and fast-response solution for alcohol detection, with a wide range of applications such as portable alcohol detectors, gas level alarms, and breathalyzer devices.

Features:

Detection Range: Detects alcohol concentrations from 0.05 mg/L to 10 mg/L
Operating Voltage: 5V ± 0.1V
Current Consumption: 150mA
Operating Temperature: -10°C to 70°C
Analog Output: 0V to 5V
Digital Output: 0.1V to 5V, adjustable with onboard potentiometer
Fast Response: Quickly responds to alcohol gas presence
Stable and Long Life: Designed for long-term usage with minimal maintenance
Good Sensitivity to Alcohol Gas: High sensitivity to alcohol vapor detection
Onboard LEDs: Indicate power and output status

Application:

Portable alcohol detectors
Gas level over-limit alarms
Breathalyzer devices
Alcohol content monitoring in various environments
