Description and How They Work:
The Disdro Acoustic Precipitation Rain Gauge uses a piezoelectric sensor to 'listen' to precipitation as it impacts the top of the gauge. The sensor gives off a voltage when it is struck by a raindrop. This voltage is used to calculate the energy of a raindrop and places the raindrop in a bin which corresponds to a raindrop size.
