S2-432-SS: Modbus Red – Far-red sensor
The S2-432-SS, Digital Modbus output, RS-485, RS-232 – Red – 645 to 665 nm (red) and 720 to 740 nm (far-red)
The S2-432-SS Red - Far-red sensor outputs a digital signal using Modbus RTU protocol over RS-232 and RS-485. The sensor features a rugged, aluminum housing that is fully-submersible and built to withstand harsh conditions. The sensor cable includes an IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement from permanent installations for maintenance and calibration. Typical applications include measuring the Red / Far-red ratio (RFR) for ecological applications, including the effect of spectral quality on phytochrome. The RF ratio influences plant height, leaf expansion rates, and other photobiology and plant morphogenic responses.
