Let us define the problem that is expected to solve

The problem definition for a clothes protection system using an automatic rain sensing unit is to provide a convenient and automatic solution for protecting clothing from getting wet in rain or other wet conditions. The system should be small and lightweight enough to be portable and easily carried, easy to use with minimal setup and maintenance required, and affordable for the target market. The system should be able to detect when it is raining or when the user is in a wet environment and deploy some form of protection for the clothing, such as an umbrella or a raincoat, in response to the wet conditions. It should also be able to retract or remove the protection when the wet conditions have ended and operate autonomously without the need for manual intervention or control by the user. The system should also provide feedback to the user, such as an alert or notification when it is deploying or retracting the protection.

NEED STATEMENT:

An automatic rain sensing unit, in order to sence the rain outside and fulfill the demands of the people by performing certain desired tasks.
