What is the purpose of rainfall sensors in irrigation systems?

Rainfall sensors play a crucial role in irrigation systems by actively measuring precipitation levels to determine whether irrigation is necessary. Their primary function is to prevent over-irrigation, which can lead to water waste and potential harm to plants due to over-saturation of the soil. When the system detects that a sufficient amount of rain has fallen, it can automatically adjust or halt the irrigation schedule accordingly, ensuring that the plants receive the optimal amount of water without the risk of excessive watering.

By effectively integrating rainfall sensors into irrigation systems, growers can enhance water efficiency, reduce costs associated with water usage, and promote healthier plant growth through better management of soil moisture levels. This automation also contributes to sustainability efforts by conserving water resources and minimizing the environmental impact of irrigation practices.
