IoT Based Refrigerator

Refrigerators are very valuable asset of beverage distribution companies and also assets that are lent to customers for the business process of selling beverage products. Because of the slow response in complaining about damage of the refrigerator from customers, so that refrigerator monitoring system is a technology that creates practical solution for monitoring the refrigerator. Integrated sensors will send data for monitoring through the internet network provided temperature, light, electric current and also can help to decide the division of tasks for technicians who will repair automatically. With a refrigerator monitoring system that uses IoT in beverage distribution companies, hopefully that a monitoring system in the refrigerator is accurate and fast with notifications using email that directly approved by technicians, providing temperature information in the refrigerator, refrigerator lights, making the schedule of the automation system which is directly submitted to the technician so that the repair process is faster.
In this project we are using DHT 22 temperature sensor to detect sensor and nodeMCU Wifi Controller To send data To cloud . here we attached OLED 128x64 Display for Status for current temperature .for cooling the inside refrigerator peltier module which attached fan. To turn on and off cooling single channel relay connected with peltier.
We can adjust temperature from mobile Application As well From Button the refrigerator Door.
