SPICE simulation of a microcontroller system that allows us to set a temperature value that must not be exceeded. The AT89C51 is interfaced with a digital thermometer DS18B20 and a serial EEPROM 24C02C. When the temperature exceeds the set value, the microcontroller activates a motor through a relay and an optocoupler NPN. When the temperature falls below the set value, the motor stops.
