This study aimed at the users¡¯ thermal comfortable and employed a Holtek HT66F2390 chip as the microcontroller to control the motors of the carrier of the heating radiator, send the user¡¯s temperature data to the ESP8266 communication module, and read the distance data to avoid the collision and so on. The electrical heating radiator device can reads the user's temperature data and transmits it to the server on the Internet. The user can control the server via an app installed on a smartphone to calculate a comfortable temperature for the current environment based on PMV. The electrical heating radiator device obtains this temperature from the server and determines the output power of heating radiation to meet the user's comfort level through a proportional-integral-derivative (PID) control algorithm with pulse width modulation (PWM) technology. |
