Microcomputer temperature controller Circuit Diagram The Automatic Temperature Control System continuously monitors the ambient temperature using a sensor and compares it with a set point temperature defined by the user. If the measured temperature deviates from the set point, the microcontroller activates heating or cooling devices through a relay module to bring the temperature back to the
