What is a water depth sensor?

Water depth sensors are also known as water level sensors. Water depth sensors are often used to measure tank levels, well depths, river depths, etc. There are many different types of water depth sensors. All of them are used to measure the water level by submerging underwater or above the water surface.

How does a depth sensor work?

A structured light-based depth sensing camera uses a laser/LED light source to project light patterns (mostly a striped one) onto the target object. Based on the distortions obtained, the distance to the object can be calculated. A structured light 3D scanner is often used to reconstruct the 3D model of an object.

Which sensors are used for depth tracking?

Depth-tracking sensors

Some companies still use a pressurized depth-tracking/ROP sensor. The pressurized ROP system works on the principle of the change in hydrostatic pressure in a column of water as the height of that column is varied. This change can then be indirectly related to a depth measurement.

Why is depth sensor used?

Depth Imaging. Depth cameras use sensing technology to infer the distance (or depth) of points in the scene from the camera.
