Sentrius™ BT7x0 Tracker / Multi-Sensor

Under Development


The Sentrius™ BT7x0 Series Bluetooth Tracker is a durable personnel-tracking solution including social distancing, contact tracing, proximity detection and RTLS tag functionality in partnership with Quuppa.  

Proximity sensors and Real Time Location Services (RTLS) are emerging as some of the most effective solutions for social distancing, contact tracing, handwashing compliance, and measuring proximity between employees in every industry. Our BT7x0 series, based on the Nordic nRF52833 chipset, offer Bluetooth 5.2 long-range, TruePoint Diversity enabled antenna system (TDAS), and a high-capacity battery, making them an ideal fit for today's critical contact tracing applications. 

They are available in two variants:

  • BT710: Social distancing alerts and contact tracing when used with Laird Connectivity gateways to log proximity data.
  • BT720: Full Real Time Location Services when combined with Quuppa infrastructure (certification pending) with sub-1m accuracy.  Allows recorded playback of tag movements and locations. 

Based on Laird Connectivity’s 20 years of Bluetooth expertise, the BT7x0 Series Bluetooth Tracker integrates critical user notifications and best in class Bluetooth performance for the most accurate location performance.  Several form factors are available and Laird Connectivity’s team of Product Development Specialists are available to quickly provide custom options.
