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.
