Powering your device

There are three different methods to power your device. Please choose the system that works best for your scenario.

USB Cable

There is a micro-USB connector on the side of the device. You can power this from any standard USB compliant port. The port must have a minimum rating of 500mA.

Keep in mind that if a building is LEED certified, it will cut power to the building at night when no one is using it. This will create a downtime event for the sensor on a daily basis. The sensor will still function properly and track data, you will just need to ignore these planned downtime events.

Alkaline

To access the batteries, the sensor must be removed from its mounting plate. The plate is held to the sensor with magnets so they just need to be pulled apart. The sensor can be removed when the plate is still mounted above a doorway.

The device accepts two standard "D" cell alkaline batteries. With alkaline battery cells the expected life of the sensor will be 3-6 months depending on the volume of foot traffic. See below for our recommended batteries:

LTC

To access the batteries, the sensor must be removed from its mounting plate. The plate is held to the sensor with magnets so they just need to be pulled apart. The sensor can be removed when the plate is still mounted above a doorway.

This device accepts two "D" size, Lithium Thionyl Chloride (LTC) batteries. With LTC battery cells the expected life of the sensor will be 1-2 years depending on the volume of foot traffic. See below for our recommended batteries:
