## Description

An alcohol sensor module for Arduino with both digital (TTL) and analog output. It detects alcohol vapour in the 10–1000 PPM range, with analog output voltage increasing proportionally with concentration. The module also responds to LPG, natural gas, city gas, and smoke. The board features a power indicator LED, a potentiometer for adjusting the digital threshold, and a simple 4-pin interface (VCC, GND, DO, AO) for direct connection to Arduino or other microcontrollers. Key Features Dual Output – Digital (TTL) switch output and analog voltage output Detection Range – 10–1000 PPM alcohol Analog Output – 0.1–0.3V (clean air) up to ~4V (high concentration) Digital Output – TTL low when threshold exceeded Power Indicator – On-board LED Fast Response – Rapid response and recovery Specifications Input Voltage – 5V DC Current Draw – 150mA DO Output – TTL (0.1V / 5V) AO Output – 0.1V to ~4V Pin Connections VCC – 5V positive GND – Ground DO – Digital TTL switch output AO – Analog signal output Ideal For Breathalyser and alcohol detection projects Air quality monitoring with Arduino Gas detection and environmental sensing Package Contents 1× Alcohol sensor module
