Advanced Rain Sampling Microcontroller

I need an advanced microcontroller setup for a sequential rain sampler. The primary function is to detect when rain begins and to manage the collection of rain into 11 to 20 bottles in a sequential manner.

Key Requirements:
- Microcontroller to detect rain start
- Control sample timing
- Manage collection into 11-20 bottles

Ideal Skills:
- Experience with microcontrollers
- Programming for automation and sensing
- Familiarity with rain detection sensors
- Ability to manage sequential operations
