A speed control fan system has been designed to enhance the comfort level of patients and conserve energy. It is extremely helpful for those patients who may not be able to shift their positions, as it continues to monitor the body temperature of the patient along with the room temperature continuously. The fan itself automatically changes speed using sensors and PWM technology, leaving the user with no work to manually do so. The fan speed is modulated by temperature in a linear and accurate way, as determined by testing with Tinkercad simulations. A manual override through a potentiometer can be used if needed, and an LCD display using an I2C adapter provides for the ability to monitor system activity. Other enhancements to improve the system further involve more advanced control algorithms, integration with wearable technology for enhanced temperature sensing, and remote control and monitoring.
