  • iBS03R

IP67 Waterproof, Bluetooth LE time of flight (TOF) distance sensing beacon. Powered by the included CR2450 battery for 1.8 to 2.8 years battery life depending on settings. Slide switch inside turns on and off.

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.

Note that this Bluetooth beacon is not an iBeacon nor Eddystone beacon. The advertising data is instead wholly used for sensor data and is sent every (configurable) 100ms to 60 mins (60 sec default). You will need an app or gateway to scan and get the advertising data. The sensor data and battery level are in the advertising data.

1.5m drop protection.
Black only.

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