| Summary: | 碩士 === 亞洲大學 === 資訊工程學系 === 107 === This study proposes a remote intelligent monitoring socket, with a temperature sensing module combined with a solid state relay (SSR) switching mechanism, and remote monitoring through the Raspberry Pi server to achieve output power and monitoring of control appliances (light bulbs, hot water bottles, etc.) Ambient temperature changes.
The user can set the ideal temperature through the webpage, the system measures the actual temperature, and uses the Proportional Integral and Derivative Control (PID) and the Pulse Width Modulation (PWM) to control the power output of the socket. This causes the temperature to approach the ideal set point to reduce electrical losses and extend the life of the appliance.
The node device uses the sensor to measure the temperature, and the data is transmitted to the server through the ESP8266 module. The server can display the measurement data of all nodes and draw a graph to let the user know the instantaneous temperature and power results.
