Step Detection System By A Way With Arduino

Description

The purpose of the project is to detect the passing of cars and people at the entrance to an orchard and a warning beep inside this house.For this project it consists of 2 modules:

• Module detection step, either of people or cars.

• Module warning step.

The requirements are:

• The step detection module, being in the garden, must have a separate power supply, in this case we have put a solar panel and a battery.

• The module must sound warning when the detection module warn you.

• The detection module is at the entrance of the garden.

• The warning module is inside the house.
