New sensor unlocks precision lighting for growers

Ledgnd

Dutch agri-tech firm Ledgnd is set to unveil a major advancement in precision lighting at GreenTech Amsterdam 2025 with the integration of Aranet’s new Light Spectrum sensor into its digital platform, MyLedgnd. The move provides growers with a real-time, wireless tool to track and fine-tune their greenhouse lighting across the entire light spectrum – from ultraviolet to near-infrared.

While most growers currently rely on PAR (photosynthetically active radiation) sensors that capture the 400–700 nm range, Aranet’s latest innovation spans a much broader 350–950 nm range. This allows for more precise light mapping, including visibility into colours beyond the PAR spectrum, which can significantly influence crop performance. For ornamental and high-value crops, where both quality and uniformity matter, this leap in data resolution could translate into measurable yield and energy gains.
