Seeed 101020044 Grove - Alcohol Sensor

Seeed 101020044 Grove - Alcohol Sensor is a complete alcohol sensor module, based on MQ303A. It has good sensitivity and fast response to alcohol.

Grove - Alcohol Sensor is a complete alcohol sensor module for Arduino or Seeeduino. It is built with a MQ303A semiconductor alcohol sensor which has good sensitivity and a fast response to alcohol, making it suitable for a breathalyzer. This Grove implements all the necessary circuitry for MQ303A like power conditioning and heater power supply. This sensor outputs a voltage inversely proportional to the alcohol concentration in air. * Highly sensitive: Making it possible to measure when the alcohol concentration is relatively small. * Outstanding measurement speed: Fast response and resumes quickly after alcohol exposure. * Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

* Dimensions: 40mm x20mm x12mm * Weight: G.W 11g * Battery: Excluded * 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) * Heater Voltage: 0.9V ± 0.1V AC or DC * Heater Current: 120 ± 20mA
