The Prolojik PS481 series Bluetooth 4.2 multi-function sensor goes beyond control and monitoring to provide sophisticated telemetry.

The Prolojik PS481 recessed Bluetooth DALI addressable multi-function sensor delivers high accuracy measurement in a discreet form factor.

The Prolojik PS481 sensor has been designed to fit our standard form-factor sensor head.

Incorporates its own PSU node and is available in a range of lens types and finishes.

This sensor offers direct Bluetooth communication, creating a mesh network system, to the Prolojik PL17x series of BLE DALI interface nodes for OEM luminaires and the GN100 Edge Gateway. This sensor adds to the Bluetooth network, allowing data collection and collation of occupancy, daylight, temperature, asset tracking and Bluetooth® BLE telemetry data to be shared via a cloud based UI or head end PC for smart analytics.
