Outdoor testing rig
I made couple of stands using 3/4 inch PVC pipes for outdoor testing. Wanted to share the pics. The sensor nodes are screwed to a metal strip at one end and the other end of this strip is clamped to the upright PVC pipe using two screws. I can loosen one screw to adjust the node’s height. I can also increase the height of the stand by attaching another PVC pipe using a coupler. The stands are cheap, light weight and can be taken apart and put together if required. On one stand, you can see a USB cable. This will be attached to a laptop to provide serial connectivity and power to the node (configured as the network coordinator). The other node will run on coin cell or external batteries.
