Project Idea
This project is designed to monitor and control the temperature of industrial devices according to user-defined limits. It uses an 8051 microcontroller and DS1621 digital thermometer/thermostat to sense temperature, display it on an LCD, and control external loads like heaters. User settings are stored in EEPROM for non-volatile operation.
