Temperature Controlled Fan

A temperature-controlled fan system can be developed using an Atmega328 microcontroller, an L293D motor driver, and a DS18B20 temperature sensor. The DS18B20 sensor accurately measures ambient temperature, providing digital readings to the Atmega328. Based on predefined temperature thresholds, the microcontroller adjusts the fan’s speed to maintain optimal environmental conditions. The L293D motor driver serves as an interface between the microcontroller and the fan, enabling efficient control of the fan’s operation. This setup ensures that the fan operates at varying speeds corresponding to temperature changes, enhancing energy efficiency and maintaining desired temperature levels. Such a system is particularly beneficial in applications requiring precise temperature regulation, such as electronic equipment cooling or climate control in enclosed spaces.
