Fabrication of an Automatic control of Refrigeration System

Abstract

Refrigeration is the process of removing thermal energy from a low temperature reservoir and transferring it to a high temperature reservoir input a requiring the input of energy. Node MCU (Micro Controlling Unit) is the main components system and partial circuit of component Arduino UNO. Node MCU is an (ESP-8266) Wi-Fi open sources IOT platform and hardware which is based on the ESP (Extrasensory Perception) 12 module. The mechanical function is control to measure RH% sensor, compressor sensor, freezer sensor. While maintained this project is basically to ensure automatically control of refrigeration system. The system is organizing ground fault and buzzer sound alert. Node MCU circuit measuring analog to digital data controlling to blynk android mobile app, APN net to server control, when the temperature is low or above then condenser fan off or on according to APN net server control
