Other Rain Sensor & Rainfall

Piezoelectric rainfall sensors and optical rain gauges are important tools for measuring rain. Piezoelectric sensors change the force of raindrops into electrical signals. When raindrops hit the piezoelectric material, they create a charge. This charge depends on the force of the raindrops.

Rainfall is a key part of the water cycle. An optical rain gauge uses light to detect raindrops. It sends out a beam of light and measures how raindrops scatter or absorb that light.

This helps measure how strong and fast the rain falls. Measuring evaporation is also important for tracking rainfall.

Evaporation

It is another important process in the hydrological cycle. It occurs when water changes from a liquid to a gas. Rainfall and evaporation are closely related. After rainfall, it can occur from the surface of bodies of water, plants, and soil.

Piezoelectric and optical rain sensors can help in understanding the relationship between rainfall and evaporation. For example, by measuring rainfall accurately, we can better predict the amount of water available for evaporation.
