In this paper, a simple alcohol detector is designed by the alcohol sensor and a MCU, including hardware design, software design and PC microcontroller software design; achieve a measure of alcohol concentration in the air exhaled. By setting different thresholds, achieve alcohol concentration exceeding the alarm, and can display real-alcohol concentration on the LCD screen; through the method of wireless communication, achieve using host computer monitor real-time of alcohol concentration by a wireless. Experiments show that the device can be used to detect the drivers alcohol concentration before their driving.It can also be used to monitor the concentration of alcohol in the air.
