Alcohol detector are the device used to measure the amount of alcohol/alcohol concentation in test subject.
Though there are various methods to do so, the most commonly used is the device based on metal oxides semiconductor which change their electrical properties upon the exposure to alcohol. This nature of metal oxide (Tin oxide, for example) is calibrated against the amount of alcohol concentration (usually measured in PPM).
The whole Alcohol Detector will be consisting of other component also like an Amp and rectifier to enhance the output of the sensing device. But the heart of such detector is the sensing device.

Explain about the effect of the time constant RC in envelope detector?
The circuit that generates signal having the shape like imaginary curve is called an envelope detector. The effect of the time constant RC in envelope detector is that the output follows the input curve and the circuit performs like a demodulator.
