Apogee Quantum Light Pollution Sensor
Measuring light pollution, the Apogee quantum light pollution sensors detect the stray light that affects plants. Trace amounts of stray light occur in the range of 340-1040nm, caused by sources including signs and infrared security cameras. And this detection ability makes it helpful for preventing morphogenic effects, such as: hermaphrodism, stem elongation, and poor flowering in sensitive plants.
Available in package and sensor options, with sensors available with unamplified, amplified, 4-20mA or SDI-12 outputs.
