A drop driven by a strong wind will have a larger amplitude than one simply falling. Of course that goes back to the OP's poor definition of the "hardness" of a rainfall. | |

One might need to do some work to correlate the nature of the pulses with both drop size and their velocity but I like this because it clearly tells you the difference between "pitter-patter" and "raining cats and dogs". | |

I once had a car with an actual, working "how hard is it raining" sensor that would start the windshield wipers on intermittent as soon as a few raindrops hit the windshield and made the wipers go more frequently or at full speed when the rain got more intense. When the rain stopped, the wipers stopped. It actually worked very well. It had a piezo sensor on the windshield and interpretation of the signal was done by the computer in the body module. It was a 2007 Hyundai Azera. | |
