In this project, we will build an IoT-enabled Smart Fridge with ESP8266 Microcontroller & multiple DS18B20 temperature sensors. With the advancement of the Internet of Things, devices are getting smarter and data collection can help make daily life easier. The Internet of Things (IoT)-enabled smart fridges or refrigerators are intelligent appliances that offer temperature optimization, diagnostics, and data collection features. This can maximize food storage and reduce product deterioration. It also provides owners with a more practical and efficient approach to overseeing their food storage.
In this project, we have built a tiny battery-powered smart device using the ESP8266 WiFi Module and a pair of DS18B20 Temperature Sensors. The device has very low power LDO to operate at lower temperatures. It also has a BMS IC to charge, manage, and protect the battery. Due to its tiny size, it can be put anywhere and requires very small space.
Regarding the data observations parts, the ESP8266 connects to a Wi-Fi network and generates a webpage. The webpage can be accessed from any Web Browser. The wepage displays the value of Battery Voltage, Battery Percentage, Fridge Temperature, and Freezer Temperature. The Web page is AJAX-based, hence data is updated without refreshing the webpage.
