Wireless temperature controlled fan for home application / Faezal Asharaff Misban

This project entitled 'Temperature Controlled Fan for Home Application' will present the design, structure, development, control and evaluation of an automatic switching the electric fan by using a temperature sensor. Generally, the wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, and to cooperatively pass their data through the network to a main location. There were some modification towards the wireless temperature sensor was carried out to improve its performance. The ideas that differ this project from others are by using "intelligent technology" such sense the temperature. Temperature Controlled Fan consists of thermostat or temperature sensor (LM35), LCD (liquid crystal display), push button switches and fan as the output. This temperature control application will read a value from a temperature sensor and determines when to switch a fan on or off according to minimum and maximum temperature limit settings. By set at the push button switches upper and lower limit, these settings can be changed. Then the limit settings and the current temperature are displayed on a I 6x2 LCD panel. At the end of project, an automating wireless sensor temperature with 315MHz working frequency is able to transmitted data to the receiver successfully.
