I have an Oregon Scientific wireless rain gauge. An irritating "feature" is battery replacement causes the history to be cleared. If that happens during the rainy season I have to write down the current total and manually add it to all future readings.
It would be nice to have a little box with a button that would run up the rain amount to the previous total.
The rain collector has a tetter totter with a thimble-size bucket at each end. When a bucket gets full the tetter totter flops over, empties the bucket, and starts diverting the collected rain to the other bucket. I believe the circuits in the collector sends an RF signal on each flop. The indoor unit must increment the current total with each signal.
If I'm right about this, one should be able to build a circuit that would emulate the collector. Specifically, a button would send an RF signal at the right frequency on each push or a series of signals if it's held down. I assume can be measured somehow or perhaps obtained from Oregon Sci.
I have a pretty good understanding of circuits and have done a bit of circuit building from schematics for hobby projects over the years, but know nothing about RF.
Any ideas?
