It has an RJ-12 connector. I measured 3.138VDC between pins 3 and 5. The weather station I got this from used two 1.5VDC rechargeable batteries so that makes sense.
How to test for the output of the other sensors I am unsure of. I don't know if it's a simple matter of measuring an output voltage or it has some other type of output? The rain bucket line plugs into the bottom of this so there is another RJ-12 jack on the underside. The RJ-12 in the pic plugged into the wireless transmitter.
