Low cost embedded weather station with intelligent system

This paper presents an embedded design of a low cost weather station. Three weather parameters; wind speed, wind directions and temperature are measured. The measured parameters are used to measure the wind chill temperature and dressing index through calculation and a build-in intelligent system. Only basic types sensors were used (a reflective optical sensor, potentiometer and a temperature sensor) so that the cost of this design is reduced. A small scale neural network was planted into the microcontroller for the post-processing. Taking the three measured data as inputs, the system gave out the dressing index as an output. All of the data were displayed on the LCD and also sent to computer from the serial port.
