In this paper describes the design and implementation of a Wireless Sensor Networks (WSN) based on XBee technology to monitor the history and current temperature information of remote locations. In this work, the microcontroller is used to compute and compare the value of current temperature and the set point values. LCD is used to display the result data. This result data is also sent to the microcontroller where the operator controls the whole process. Then, the signal passes to the relays to On-Off case of the fan for maintaining the correct temperature.
