Product Description

Description:

This alcohol sensor is suitable for detecting alcohol concentration in your breath, just like your common breathalyzer. The sensor provides an analogue resistive output based on alcohol concentration. When the sensor is present in the environment in which the alcohol vapour, the sensor's conductivity increases with the concentration of alcohol gas in the air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal.


Features:

High-quality double panel design, with power indicator and TTL output signal

Have DO switch signal(TTL) output and AO analogue signal output

TTL output signal for low level effectively. (when the low output electric signal lights at ordinary times, can be directly connected single-chip microcomputer or relay module)

Analogue output voltage with concentration, the higher concentration, the higher voltage

Has better sensitivity to the liquefied petroleum gas, natural gas, city gas, smoke

Has long service life and reliable stability

Rapid response recovery features

Specifications:

Input voltage: DC5V

Power consumption (current) : 150 mA
