The Aranet PAR Sensor is a wireless device designed to measure photosynthetically active radiation (PAR) within the 400–700 nm range, providing accurate insight into the light available for plant growth. Ideal for greenhouse and controlled growing environments, it enables growers to optimise lighting strategies by balancing artificial and natural light. Fully compatible with Aranet Cloud, the sensor supports real-time monitoring and the calculation of Daily Light Integral (DLI), helping to improve energy efficiency and ensure consistent crop development. Supplied with a holder for stable positioning, it offers a reliable solution for precise light management.
