OSEPP AGAS-01 MQ-3 Alcohol Gas Sensor Module
The OSEPP AGAS-01 MQ-3 Alcohol Gas Sensor Module is a high-performance sensor designed to detect the presence of alcohol vapor in the surrounding environment. Based on the MQ-3 sensor, this module offers reliable detection, making it perfect for breathalyzer devices, alcohol safety monitoring, and other air quality monitoring applications. The module is highly sensitive to alcohol and can detect a wide range of alcohol concentrations, providing accurate and fast response times.
Features:
- High sensitivity to alcohol vapor, making it ideal for breathalyzers and alcohol detection systems.
- Simple analog output, compatible with microcontrollers like Arduino.
- Fast response time and long-term stability.
- Easy-to-integrate design for electronics projects.
- Operates at 5V for compatibility with standard development environments.
- Detects multiple gases including LPG, i-butane, methane, hydrogen, and smoke.
- Low power consumption for battery-operated applications.
