SPARK’s Presence Detection Kit (PDK), powered by the SR1120 LE-UWB transceiver, delivers low-power, robust sensing for connected devices. Its low-energy ultra-wideband (LE-UWB) technology helps designers overcome the high power consumption and interference challenges of Bluetooth, Wi-Fi, and conventional UWB.

LE-UWB supports unidirectional and bidirectional communication, ultra-low-power beaconing with configurable detection zones, and line-of-sight Time-of-Flight (ToF) measurement for precise proximity and distance sensing. SPARK reports that its LE-UWB technology consumes over 10× less power (30 µW at 4 Hz) than Bluetooth/BLE beaconing and delivers more than 20× higher power efficiency than standard UWB.

SPARK provides an energy-optimized firmware stack for presence detection, including APIs for beaconing, ranging, data transmission, and OTA firmware updates. Reference hardware kits, demo applications, and GUIs allow engineers to evaluate detection performance, adjust detection zones, and accelerate prototyping. The PDK hardware is selected to optimize performance, power, and cost, and integrates across a broad range of MCUs and software architectures.

Presence detection kits are available now. For details on board and kit configurations, contact NA_sales@sparkmicro.com.
