Ambient luminosity transmitter

visiblephotodiodesilicon

Overview
Specially designed to detect sunrise and sunset (twilight detection) or to measure lighting illuminance, this transmitter ensures compliance with exposure thresholds required in agro‑ecology for animal welfare and optimal plant growth. It features a remote sensor option, low drift for stable long‑term measurements and includes a power supply for immediate installation.

Key features

• Twilight detection (sunrise/sunset) and illuminance measurement
• Remote sensor for distributed measurement
• Low drift for reliable long‑term readings
• Compatible with LoRa SPY U connected sensor
• Direct connection with Nano SPY U to the transmitter's analogue output
• Connection via analogue output or IP67 Binder cable
• Output: 4‑20 mA; power supply included

Stability
With low drift over time, the transmitter provides consistent measurements suitable for lighting control applications where accuracy must be maintained without frequent recalibration.
