Weather Station


History

    This project is one of many others I had made to control my house with rules, web interface, logger and many more. This one is a weather station that reports almost anything about the external environment. I bought mechanical part of the wind sensor at http://www.aag.com.mx/indexaag.html I had to remove all the electronics that came with it and replace them with my own. 

The lightning detector is very simple but it works very well if you have a REAL ground, not your ground of your electronic part, and don't worry about the 9v battery, after 2 years it is still working. The humidity and temperature sensors are the same ones I had used in the barometer project. I drilled a 3cm hole in 5 soup bowls, mounted upside down. The top and bottom soup bowl doesn't have holes. The sensors are place in the middle of those and this way the sensors are protected from sun heat and the air could pass through.  The light sensor is done with a simple LDR and that does a good job to tell my house to go into night mode.  Rain fall sensor is a simple tipping bucket that gives pulse to the MCU and with a simple formula you can know how many millimeter of rain fell.

    why not adding ethernet support to send logs to some webserver to get beautiful graphics later?
