L02S-BCN
Smart Sensor Beacon

The L02S-BCN is an intelligent, cloud-connected Smart Beacon, designed to meet the demands of industrial and commercial sensing and connectivity. The L02S-BCN demonstrates what’s possible when established and trusted design meets Bluetooth cloud connectivity.
The L02S-BCN Smart Beacon provides:
- Two-way communication with cloud confirmation and OTA updates
- Secure data transport with encrypted payloads and authenticated identity
- Flexible deployment and roaming using Blecon Hotspots
- Time-based insights with globally synchronised timestamps
- On-device intelligence with support for embedded AI/ML
Powered by Blecon Networks
The L02S-BCN connects to the cloud through Blecon Networks via any nearby Hotspot. No pairing. No custom gateways.
Blecon Networks enable:
- Secure device identity, bi-directional communication, geolocation and time services
- Flexible deployment of network coverage using roaming hotspots—phones, laptops, or gateways—without the need for pairing
- OTA updates for firmware and ML models
- Integration with cloud services out of the box using developer-friendly APIs

Next Generation Hardware
At the core of the L02S-BCN is the Nordic Semiconductor nRF54L Series system-on-chip (SoC) , with high performance, low power operation, and advanced Bluetooth capabilities. Paired with Blecon, it enables reliable data collection and advanced applications.
The L02S-BCN includes sensors for temperature, humidity, pressure, and 3-axis acceleration, all housed in a rugged IP67-rated enclosure. Powered by a CR2477 coin cell battery, it’s suited for a wide range of applications, from fixed installations to mobile assets.
