Both are BLE 5.1 scanners with PoE and Wi-Fi in the same IP54 enclosure. LEN-2 adds environmental sensing (temperature, humidity, pressure, TVOC) and motion detection, and has a 3 W supply rating against 2.5 W for LEN-1.
Temperature (0–60 °C), humidity (0–100 %RH), pressure (0.3–1.2 bar) and TVOC (1–500 VOC points), plus motion detection.
RSSI-based proximity positioning is typically 3–5 m. Results depend heavily on environmental conditions, layout, wall materials and deployment design.
Up to 100 m. Signal propagation depends heavily on environmental conditions. The optional external antenna improves sensitivity, up to −92 dBm.
Yes. Data can go to the Sentrax Solix platform or to a local / client MQTT broker, with TLS secured connections and redundant broker support.
Through PoE (802.3af) over RJ45 or a 12 V DC adapter (12 V / 1.5 A), on a wall or ceiling with the wall / ceiling mount and screws.
Yes. The embedded Configuration Portal lets you check status, change parameters, back up and restore settings and upgrade firmware. Remote tag configuration and update are supported.
CE. FCC certification is pending.
