An RFID sensor tag, capable of transmitting a unique identifier and the associated weight measurement data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag, has been released by Farsens. The Atlas features four channels for load cells with measurement ranges from 0 to 900kfg per channel.

The tag is offered in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960MHz band. The reading distance for the battery free magnetometer tag is around 1.5m and it can be embedded in a wide variety of materials such as plastics or concrete. Evaluation kits are also available.

The Atlas can be used without batteries, allowing for a wide range of opportunities monitoring weight in applications where the accessibility is restricted. The tag is also suitable for users that have RFID infrastructure in place and want to monitor weight without the cost of wiring or maintenance.

Atlas tags are suitable for warehouse inventories, especially for granulates and liquids. Here stock keeping units are generally big but the shop floor orders are small and managers find themselves with a variety of containers with unknown quantities of product. The devices help managers quantify their inventories in a matter of seconds.
