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 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2024-11-08 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2024-12-17 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-01-03 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-03-19 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-04-15 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-04-30 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-06-23 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-08-02 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2025-09-12 https://elecena.pl/product/27185549/seeed-101020044-grove-alcohol-sensor 2026-03-10
