How do you measure light?
Radiation sensors measure the flux of radiant energy—the energy that drives plant growth, warms the earth, and lights our world. The properties of radiant flux depend on the wavelength of the radiation.
Light Sensor Design
LI-COR sensors are weather resistant, low maintenance, and cosine corrected. From the shape of the crown to the photodiodes and optical filter glass, every aspect is the result of scientific inquiry.
Light sensors integrate with RX stations and HOBOnet sensor networks via analog sensor adapters, either the Analog Module or wireless Analog Mote, which sends data via Bluetooth wireless. The sensors come with bare leads that wire into the analog adapters. Note that the LI-COR light sensors require a 2420 Amplifier to connect to the analog module.
Pyranometers are sensitive to the broadest waveband. Photometric sensors measure visible radiation (light). Quantum sensors measure Photosynthetically Active Radiation (PAR)—the radiant energy used in photosynthesis.
