The aim of this project is to energy saving system able to optimize power management and energy efficiency of a home heating plant. The continuous control of temperature is making efficient energy saving as well as controlling the room temperature at home. The system uses a sensor to control the heat by switching on the fan. We can use this mostly in industries, homes etc. Zigebee provides a wireless communication network, the information is transferred point-by-point to the required place.   The controlling device of the whole system is a Microcontroller. Microcontroller acts an intermediate between input and output modules and acts accordingly on the output modules from the input received as in the way it is programmed. Here, the Microcontroller get input from temperature sensor. If the temperature is more in the room it gives data to the microcontroller. The microcontroller process it and make the fan will be switches ON using Relay. The monitored data is sent to PC/Laptop using Zigbee wireless communication. The Microcontroller is programmed in Embedded C language.

 

The main objectives of the project are:  

1. Based on temperature value, fans are to be controlled in room.
2. Controlling data is sent to PC/Laptop using Zigbee Modules.

  This project provides us with the learning’s on the following aspects:  

1. Interfacing sensors and zigbee modules with Microcontroller.
2. Embedded C programming.
3. PCB Design and development.
