Apogee Red - Far-Red sensors combine two photodetectors designed to measure wavelength ranges and peaks that approximate phytochrome absorption. The red / far-red ratio can be calculated from these measurements. Red and far-red wavelengths are of particular interest because they influence photosynthetic and morphogenic activity. Phytochrome pigments sensitive to varying ratios of red and far-red light provide information to the plant about its light environment.
The S2-131-SS Red-Far-Red Sensor is a specialized light sensor designed for measuring red and far-red wavelengths, typically in the range of 600 to 800 nm. This sensor is often used in horticultural applications to assess light conditions critical for plant growth and development.
