Description

Alcohol Ethanol Sensor price

MQ-3 Alcohol Ethanol Sensor price Module Breathalyser Gas Detector Ethanol Detection For Arduino. MQ3 is one of the most commonly used sensors in the MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type of sensor.

Metal oxide sensors are also known as Chemiresistors, because sensing is based on the change of resistance of the sensing material when exposed to alcohol. So by placing it in a simple voltage divider network, alcohol concentrations can be detected.

Feature:(MQ 3 Alcohol Ethanol Sensor price)

1. MQ 3 Alcohol Ethanol Sensor has DO switch signal (TTL) output and AO analog signal output.
2. TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can directly connect single chip microcomputer or relay module)
3. Analog output voltage is with concentration and the higher concentration the higher voltage.
4. It has better sensitivity to the liquefied petroleum gas, natural gas, city gas and also smoke.
5. Has long service life and reliable stability
6. Rapid response recovery features
