Summary of Refregirator Temperature Controller Project (Save Your Electricity Bill)
This article outlines a refrigerator temperature controller project using a microcontroller to reduce power consumption by eliminating unnecessary internal heater usage. The system utilizes a DS18B20 sensor to monitor temperature and controls the compressor via preset ON/OFF thresholds set through four buttons. Developed in Mikro C and tested in ISIS Proteus, the device displays readings on two 7-segment displays and saves settings upon button activation.Parts used in the Refrigerator Temperature Controller:
- Microcontroller
- DS18B20 Sensor
- Two 7 Segment Displays
- Four Buttons (Mode, Up, Down, Save)
- 4.7k Pullup Resistor
- Mikro C Programming Language
- ISIS Proteus Software
This Project is Development of Thermo meter project.

Mainly we use Mikro C Programming Language in this Project and ISIS Proteus Software use for testing Purposes.
How to Work Refregirator Temperature Controller.
You know about Refregirator has Internal Heater Coil inside the freezer Area. These heater use for melt ICE inside the freezer.Heater take lot of power units consumption for melting ICE.This is effect highly for refregirator total power consumption.We cut that extra power Units using this Refregirator Temperature controller.This project is very effective for Chest Freezer.
We placed DS18B20 Sensor inside the Refregirator and every time it measure refregirator Inside temperature on Two 7 SegmentDisplay.If Refregirator Inside Temperature reach to Preset ON Temperature and Refregirator Automatically Power On.When InsideTemperature reach Preset OFF Temperature Automatically Refregirator Power OFF.We can setup ON and OFF Temperature Using 4 Buttons.
We use Four Buttons for Setup ON/OFF Temperature in this Refregirator Temperature Controller
1) Mode Button
2) Up + Button
3) Down – Button
4) Save Button
Mode Button
Mode 1 (Press 1 time)
You Can Adjust Refregirator OFF Temperature using + and – Buttons.
You Can Save Changes using SAVE Button(Hold).
Mode 2 (Press Two times)
You Can Adjust Refregirator ON Temperature using + and – Buttons.
You Can Save Changes using SAVE Button(Hold).
We Should Use 4.7k Pullup Resister for DS18B20 .
This Project Succesfully Tested in Real Hardware and Work very well.
