Alcohol in a person's bloodstream passes through the lungs into a person's breath and can be detected using this test. It is very hard to fool!
It depends on the device. Brethalyzers measure electricity created by the presence of alcohol, while blood work uses laboratory testing procedures.
During respiration, blood in the lungs gets vaporized. It's the breath with the vaporized blood that gets measured for alcohol content.

What is alchol detector explain?
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.
How does a battery detector works?
i think it detect the voltage left by the battery
How is a detector used on people with alcohol and how does it work?
When you drink, you exhale a certain amount of the alcohol in your breath. This is how blood alcohol content (BAC) is measured by breathalyzers. You blow into the machine, if analyzes how much alcohol is in your breath, performs a mathematical equation, and determines how much alcohol is in your bloodstream.

Does a homemade metal detector work better over soil or sand?
A homemade metal detector works better over sand. It works the Same both of them but it takes a longer time to find the metal in the soil. Try it at home just grab soil sanda radio and a calculator. Also a piece of metal .
