Tipping Bucket Rain Meter

This is an automated rain meter generating a countable pulse that can be converted to millimetres of rainfall.

CalibrationThere will be subtle differences in calibration based on the print, assembly and screw settings, but I would assume if printed to 100% scale, the catchment area will be consistent. Calculating the catchment areaThe corners are curved at a radios of 20.8mm, so if we calculate the surface area of the rectangle less the four corners, we should get the correct surface area catching the rain. So 66.6 x 129 mm results in 8591.4mm total square are less the four corners of 371.39 that leaves us with an effective collection area of 8,220 mm squared and this is equivalent of 8.22 ml of water when we get 1mm of rainfall.
