This project's primary goal is to use Arduino and the Internet of Things to construct a solar-powered smart dehydrator system. The system used to preserve food using solar energy through a charging circuit, solar energy is stored in the battery and used to power the project. Through an insulated tube, the heat from the sun is transferred to the heating chamber. Due to this procedure, the heating chamber will become heated, preventing bacterial growth and removing moisture from the meal. It aids in the longer-term preservation of food goods. The Arduino microcontroller is the primary controlling component of the entire system. The Arduino microcontroller receives input from temperature sensors, an exhaust fan with a relay, an esp8266 Wi-Fi module, and an LCD display. The inside and outside temperatures of the heating chamber are measured using temperature sensors. The sensor data is continuously read by the Arduino controller and shown on the LCD. When the temperature rises above 45 degrees, Arduino will use a relay to turn off the exhaust fan. Additionally, the user can operate the exhaust fan from a mobile device using the Blynk app and WI-FI. Here, the relay acts as a switch to turn on and off the fan.
