A complete alcohol sensor module for Arduino.

Overview

It is built with MQ303A semiconductor alcohol sensor. It has good sensitivity and fast response to alcohol, making it suitable for building a breathalyzer. This Grove module implements all the necessary circuitry for the MQ303A, such as power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in air.

Note: The sensor value only reflects the approximated trend of gas concentration within a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If your project is aimed at obtaining the gas concentration at a very precise level, then we do not recommend this gas sensor.

Features

  • Input Voltage: 5V
  • Working Current: 120mA
  • Detectable concentration range: 20-1000 ppm
  • Grove Compatible connector
  • Fast response and resumes quickly after alcohol exposure
  • Long life
  • Compact form factor
