Circuits DIY – How to Make a Weather Station!

weather-station

Here’s an impressive weather station project you can make that will show you bunch of great current weather conditions.  I do highly like the graph part, it can be developed even further to allow internet remote monitoring and more.

Now this was a huge project! All sensors had to be fully tested one at a time, wireless communication had to be perfect, various LCDs were tried. Nevertheless, here’s the result: hope you enjoy it!

The circuit may be powered by a small 9V battery, but you’d better take a couple of AA-batteries. A 6-pack will last a several months. Consumption for the base station is around 8 to 9 mA whilst active and only 2 to 3 mA in sleep mode (LCD remains on.) The transmitter takes slightly less.

The receiver (base station) is active during 5 seconds & then goes to sleep for 45 seconds. The transmitter takes a nap every 30 seconds or so.
