Overview:

This Alcohol Grove Sensor is a complete alcohol sensor module for Arduino. It is built with the MQ303A semiconductor alcohol sensor. This sensor has excellent sensitivity and is able to return rapid responses when exposed to alcohol. Therefore, it is suitable for making a "Breathalyzer". The module implements all the necessary circuitry for MQ303A such as power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in air.

This product works on 5V only, so it is therefore not suitable for 3.3V boards like SODAQ and the Seeeduino Stalker.

 

Features:

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

 

Specifications:

  • Power requirements: 5 VDC @ ~120 mA (heater on)
  • Detection Gas: Alcohol
  • Concentration: 20-1000ppm Alcohol
  • Interface: 1 TTL compatible input (SEL), 1 TTL compatible output (DAT)
  • Dimension: 40×20×12mm
  • Heater Voltage: 0.9V ± 0.1V AC or DC
  • Heater Current: 120±20mA

 

Application Ideas:

  • Alcohol level over-limit alarm
  • Stand-alone/background sensing device
  • Environmental monitoring equipment
