Christian Brandt has made a very nice climate monitoring and notification system for my mosquito room. It checks temperature and humidity every minute and sends me an email if either of these two parameters are out of the permitted interval. In addition, it logs the data into a google spreadsheet (yes, you can now monitor climate in my insectary too! 🙂 ) every 10 minutes. Doesn’t take up much space at all, all it needs is a power source and a wi-fi connection.
If you’d like to build one for yourself, ask Christian how!
