Project Description

Introduction

This Social Distancing Tag (SDT) is a reference application leveraging the SmartBond Wireless Ranging (WiRa) SDK. The application targets mainly, but not exclusively, wearable devices allowing its users to be warned in the case that they do not comply with social distancing recommendations. In the COVID-19 pandemic context, the SDT users should not gather within a physical distance lower than 1.5m. The users in a professional environment should be warned they are not complying with the recommended physical distancing.

Thanks to its high level of integration and the support of advanced ranging features, the DA1469x product family is a great fit for this application.

The SDT application is built on top of the SmartBond Wireless Ranging (WiRa) SDK, for more information please visit the SmartBond™ Wireless Ranging SDK page.
