It’s common knowledge by now that social distancing is a key element of preventing the spread of COVID-19. To that end, Maggy, a Belgium-based start-up specializing in Bluetooth-enabled, rechargeable, social-distancing devices, has chosen a Silicon Labs Bluetooth System-in-Package (SiP) module to enable a new, compact wearable that warns users when the distance between people becomes too small and could pose a risk of COVID-19 infection transfer.
Maggy created the device as a safety measure for organizations seeking to help protect employees and visitors against COVID-19 in workplace settings, including industrial, logistical, and pharmaceutical sites. Right out of the box, users can wear the Maggy as a lanyard or place it in their pocket and immediately sense vibrating and beeping if they become too physically close to another person with a Maggy. Additionally, Maggy’s profiled endpoint allows wearers to engage common machine buttons, like elevators or light switches, without coming in direct contact.
The high-performance accuracy of the Maggy devices is made possible by Silicon Labs’ BGM13S Bluetooth SiP Module, which works in combination with received signal strength indicator (RSSI) localization technology and a proprietary algorithm developed by Maggy to filter out potential false measurements.
Silicon Labs touts the BGM13S as the world's smallest Bluetooth SiP module, enabling IoT device makers to add Bluetooth to designs quickly while meeting all regulatory certifications. Silicon Labs offers an extensive range of SoCs, modules, and software tools designed for ease of use.
Privacy was a key part of the design process. Users are not required to register when using the device and no personally identifiable data is saved, thus meeting the EU’s General Data Protection Regulation (GDPR) guidelines. The device is based on Bluetooth 5.1 and achieves accuracy within 15 centimeters (5.9 inches) between two people.
The Silicon Labs’ EFR32BG13 Series 1 Module powering the Maggy device is designed for Bluetooth Low Energy and Bluetooth mesh applications where ultra-small size, reliable high-performance RF, low-power consumption, full modular certification, and easy application development are key requirements.
