Set 331. micro controller based refrigeration control system

  1. 1. Micro controller based refrigeration control system The main purpose of the project is to monitor and control the Refrigeratortemperature by using a temperature sensor. This sensor monitors the temperature of therefrigerator for every few minutes; if the temperature of the refrigerator decreases thelimit then it automatically turns OFF the device. Temperature Monitoring systems are in huge requirement and we definitely canfind their advantages in many industrial sector and also in residential sector. We can findmany kind of temperature monitoring systems for different uses but the major challengeis to design a very simple, User-friendly and cost effective system. We developed this project, which is relatively inexpensive to sense thetemperature. The temperature is read by the ADC (Analog to Digital Converter) moduleof the microcontroller Unit. This ADC data is processed and converted into the actualtemperature reading by the microcontroller. This processed data is sent to the LCD foruser display. The door-opening sensor is also interfaced with the controller when the door ofthe refrigerator is opened then it senses and it gives a buzzer alert.The objectives of the project include:1. Read the temperature in real-time.2. A buzzer for alerts.3. LCD display.www.mycollegeproject.com Ph: +91 9490219339, 040-23731030Ameerpet: A-8, 2nd floor, Eureka court, beside Image hospital, Ameerpet, HYDERABAD 73.Santoshnagar: Opp: Magna Hypermarket, Santoshnagar X-Roads,HYDERABAD – 59.
  2. 2. The project provides us exposure on:1. Initialization of ADC module of microcontroller.2. Interfacing Temperature sensor to controller.3. LCD interfacing.4. Embedded C program.5. PCB designing.The major building blocks of this project are:1. Regulated power supply with voltage regulator.2. Temperature sensor.3. ADC module.4. Microcontroller.5. Door opening sensor.6. LCD display7. Buzzer.Software’s used: 1. PIC-C compiler for Embedded C programming. 2. PIC kit 2 programmer for dumping code into Microcontroller.www.mycollegeproject.com Ph: +91 9490219339, 040-23731030Ameerpet: A-8, 2nd floor, Eureka court, beside Image hospital, Ameerpet, HYDERABAD 73.Santoshnagar: Opp: Magna Hypermarket, Santoshnagar X-Roads,HYDERABAD – 59.
