Since day one our ZIGPOS Badge comes with an acceleration sensor (the ST LSM9 series) on board to recognize movement of the Badge for high precision positioning. When no movement is detected, the Badge is in sleep mode to save energy. This is a key functionality to energy efficiency.

Starting with our newest firmware, we are introducing the Enhanced HasMoved Value, which is an indicator to estimate how massive the acceleration of the Badge was.

To keep the channels free and to be able to scale the user scenarios to 1000+ Badges, we are not interested in transmitting the raw sensor data over the air. Instead we are preprocessing on the Badge. The following signal processing is done on the Badge.
