Abstract: A wireless sensor system is a system that provide and utilising any number of sensor modules, any number of communication devices, The sensor modules have sensors for sampling data, and wirelessly transmit data to their corresponding communication device, and receive transmission instructions from the same. This project present an introduction to wireless sensor system, Types of sensors and describe its working in general form. Next presents a design of wireless system for sensor temperature. The main purpose of this research is to design a model forreading and measuring temperature signals. The system reads data from sensor and then transfer it to the computer to be read in MATLAB program.

Keywords: Sensor, TMP36, XBee Module, Temperature Wireless Sensor.
