In recent months (3 to be exact), two store-bought wireless temperature gauges have failed. Not sure why they failed, and I don’t really have a way to diagnose what failed in them – but the display shows the outside temp as being —. So, tiring of not being able to fix it, I’ve decided to build my own. After some discussion on the Arduinohome yahoo group (https://groups.yahoo.com/neo/groups/arduinohome/conversations/topics), I have decided to build two separate systems. One is a wired system, using a single arduino nano and the other is a wireless system using two.
I’ve placed orders for the necessary equipment (or what I believe the necessary equipment will be). The wired system parts i bought from ICStation, and they’re on the way. For the wireless system, Phil Grant introduced me to the Jeenode boards, and how he used them to do exactly what I was wanting. “Chuck” then pointed me to a US site that sold the Jeenode boards (Modern Devices – http://moderndevice.com/ ). I quickly ordered two of these (on July 3rd). They arrived earlier this week – not sure exactly which day as I was out of town for a couple days.
I still don’t have the rest of the equipment, and haven’t done anything other than open the shipping box to see the two boards, but I’m on my way.
