It’s been a while since i posted the original concept of the anemometer and much more development went into it after that.
I have now made a propper PCB and gone to a 20X4 LCD as well as probably tripling the lines of code.
The code now displays a speed for every revolution of the vane. It’s a little hard to read in windy conditions so i also added an average reading which is an average of the last 10 readings. I also added a feature into the code to output the average value via a serial port on the chip. The serial port data is pumped into a MOXA nPort server, which is mapped to a virtual serial port on my server over the internet (some kilometers away). The data is logged via a PHP script, further averaged and pumped into an rrdtool database at regular intervals. This gives me the ability to easliy see what the conditions are like from anywhere in the world. It’s geeky i know, and it was more of a ‘because i can’ feature rather than a requirement.
Feel free to check it out – http://www.hux.net.au/anemometer It’s basic but does the job.
