Summary of AVR Microcontroller based Temperature Monitoring and Control System
This project describes an AVR Microcontroller-based Temperature Controller using an LM35 sensor to measure temperature and a 16x2 LCD to display temperature set points, heater status, and current temperature. The system controls a heater by switching a 12V relay on and off based on temperature settings adjusted through tactile switches. It is suitable for applications like automatic temperature-controlled soldering stations. The project includes circuit design, PCB layout, and simulation files for easy implementation and testing using Proteus software.
Parts used in the AVR Microcontroller based Temperature Controller:
- Atmega 8 Microcontroller
- LM35 Temperature Sensor
- 12V Relay
- 16x2 LCD
- BC548 Transistor
- 1K Ohm Resistors
- Tactile Switches
AVR Microcontroller based Temperature Controller, it uses LM35 Temperature Sensor for measurement of temperature and 16×2 LCD is used to display temperature set point, Heater Status and current temperature, It controls temperature by turning on and off of the heater using relay.
This project is very useful for controlling of temperature, It can be used for soldering station to make it automatic temperature controlled.
In this project two switches are used for setting the set points. You can try this project using Protius simulation. Circuit diagram, Layout is provided with code. Download respective files.
