This is a Cooler system running on atmega 32 where the motor is turned on once the temprature is over 35 and there is a buzzer that confirms on temprature. There is also 2 seven segment and LCD that represents the temprature on it to ensure about the correct temprature. Here there is a picture of proteus file for the project.
Details:
- Cooler, buzzer and LED will be on when temperature is more than 35C and off when less than 35C.
- Temperature should be appeared on LCD first row and also in seven-seg.
- Cooler speed (duty cycle) should be appeared in second row.
- Cooler system is consists of 5volt DC motor, when the range of temperature is from 35c to 50c the cooler Dc volt should be from 2.5 to 5 volt.
Note: The callibration of the temprature may vary from one person to another so make sure that its callibration is correct!
