Aranet Apogee PAR Sensor SQ-500

Research-Grade Light Measurement for Sunlight, Greenhouse, and LED Installations

The Aranet Apogee PAR Sensor SQ-500 measures Photosynthetically Active Radiation (PPFD/PAR) across a spectral range of 400 to 700 nm, providing highly accurate light data for sunlight, greenhouse, and LED installations. It’s designed to validate light levels and support data-driven decisions when optimising a facility’s lighting strategy.

Why It Matters

Photosynthetically active radiation is one of the most important drivers of plant growth, yet light levels can vary significantly between fixtures, locations within a facility, and natural daylight conditions. Without accurate, consistent PAR measurement, growers risk under- or over-lighting their crops, leading to wasted energy, inconsistent growth, or reduced yields. Validated, research-grade data removes the guesswork from lighting decisions.

The kit includes the Aranet Apogee Transmitter, the Apogee Full-Spectrum Quantum Sensor (SQ-500), and the Apogee Solar Mounting Bracket with Leveling Plate, allowing the sensor to be levelled and positioned correctly for accurate readings. Like other Aranet Pro series sensors, it integrates with the Aranet base station and Aranet Cloud for remote data access.

The Aranet Apogee PAR Sensor SQ-500 delivers the research-grade light data needed to validate and optimise lighting strategy across sunlight, greenhouse, and LED-lit environments.
