Rainfall monitor based on raspberry pi and 28BYJ stepper motor

An outdoor bucket gets filled with rain water and triggers a rotation on gpio pin which further executes a sequence of stepper motors conditionally.

Result is an awesome display of rainfall reading.

28BYJ is very accurate with gear train and requires very little current that can be run with just an uln2003 driver.

It is a very innovative concept , due to NDA details cannot be provided.
