HN-SN01

FEATURES

Key features

True illuminance

Measures sky illuminance at the pole instead of guessing from a city-wide clock.

Schedule correction

Dimming curves follow actual dawn, dusk and storm conditions.

LoRaWAN uplink

Reports through the same gateway network as the lighting controllers.

Self-powered option

Solar variant for poles without spare power capacity.
