Yet another rainfall meter. Sensitivity/resolution is about 1,25ml / 0,173mm/m2 per pulse with 5x5x2magnets. Except for printed parts, You'll need:

* 2x 5x5x2 magnets, N38 minimum;
* 4x M3x16 screws
* 2x M3x20 screws
* 1x M3x35 screws
* 4x 3x16 or 3x20 wood screws with triangle head
* Unipolar Hall sensor & pcb for it (everything on PCB except hall sensor is optional)
* C1 & C2 - 1206, 100uF, 16V
* IC2 - DS18B20 (WARNING: pinout is reversed on PCB)

Surface area is about 7238mm2, so multiplier is 138,15. In my case bucket tips when filled with about 1,25ml, but You should calibrate it and get specific values for your print: run any known quantity of water through the meter, divide it by number of pulses it generated, multiply it by 138 and there, amount of water per m2 per pulse.
