Alcohol Detector mini project using PIC Microcontroller
PIC18F series microcontroller is used for the alcohol detection system. MQ series alcohol sensor interfacing with PIC18F4550 is done in this project. Then PIC microcontroller compares this value with the threshold limit this threshold limit can be 30% or 40%. The alcohol Detector mini project using PIC activates a buzzer and relay once this threshold limit is crossed. This Buzzer and Relay remain on as long as the alcohol percentage is more than the desired limit. ₹ 3,450 Project Code: 3094 Order Now Description of the project: Whenever the alcohol level goes down then the buzzer is turned off. We have used a small buzzer in Bus and Truck Drunk Driver Alert Using the PIC project. But you can connect a large volume buzzer to the relay. The Buzzer in…
