Suitable for applications such as trash can, toilet paper, sanitiser, inventory monitoring or industrial automation.

Short (40-1300mm) and long distance (40-3000mm) modes. The short distance mode is the default which consumes less power and is more immune to the ambient light level.

+-25mm accuracy with a 27 degree field of view. The error may exceed 25mm when the target is transparent liquid because the bottom of the container will also reflect the light. In this case make sure the bottom of the container is black or non-reflective.

An Android configuration app allows changing of transmit power level and advertising period.
