The main aim behind developing this device is to develop a multifunctional unit which can provide water cooler along with air conditioning. DHT11 is uses to measure the temperature and humidity of room and will be display on LCD display. DS18B20 module is use to detect the temperature of the water at tank and will be display on LCD. When the water goes though the copper pipe. This cool water is pump into the water tank which uses to run the Air cooler. And also, we can attach the exhaust fan. By using fan, we can spread the cool air in the room which will act as an air conditioner. This air conditioner system consists of filters to filter the air. The whole system works on microcontroller which is interfaced with input and output modules.      

 The objectives of the project include:

1. Design a thermoelectric Based Multifunctional Device Which Can Provide Water Cooler Along with Air Conditioning.

     

The major building blocks of this project are:  

1. Power supply.
2. PIC Micro controller.
3. DHT11 (Temperature and humidity sensor).
4. Exhaust Fan.
5. Room (Chamber).
6. Water tank.
7. Copper Pipe.
8. DS18b20 temperature sensor.
9. LCD display.
10. Water pump motor.
11. Crystal oscillator.
12. Reset button.
13. LED indicator.

       

Software’s used:

1. PIC-C compiler for Embedded C programming.
2. PIC kit 2 programmer for dumping code into Microcontroller.
3. Express SCH for Circuit design.
