Description

How the alcohol tester works:
When the gas sensor does not detect alcohol, the level of pin 5 of A is low. When the gas sensor detects alcohol, its internal resistance becomes low, so that the level of pin 5 of A becomes high. A is a display pusher, it has 10 output terminals, each output terminal can drive a light-emitting diode, the display pusher A determines the number of stages to light up the LEDs in turn according to the level of the 5th pin, the higher the alcohol content The larger the number of stages that light up the diodes is. The top 5 LEDs are red, indicating that the safety level is exceeded. The bottom 5 LEDs are green, indicating a safe level, with an alcohol content of no more than 0.05%
