Here’s my new prototype for sensor nodes in the house:
It has an SHT11 temperature/hunidity sensor, an LDR, and a PIR motion sensor. Prototyped using a JeePlug, of course. Ports 2 and 3 are still unused. Note that this little board can also be plugged into ports 2/3 or even turned around – all configurations will work (by adjusting the port numbers accordingly).
Here’s a silly mounting option, which will have to do for now:
This setup is attached inside a bookshelf under the top panel, roughly pointed so the motion sensor covers the room. Not shown is the power connection from a 5..12V wall-wart (I’ll look into battery mode at a later date).
Totally crude, but it works and lets me easily detach the unit between tests.
Here’s another prototype based on old “plugs” I had lying around and a JeeNode v2:
This setup will be used instead of the earlier “pulse” design described in these posts. If there is interest, I can design a little board for it handling either PIR module.
