Overview

This alcohol sensor is suitable for detecting alcohol on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.

Features

  • High sensitivity to alcohol and small sensitivity to Benzine .
  • Fast response and High sensitivity
  • Stable and long life
  • Simple drive circuit
