The RAYN Multi-Sensor (RMS) measures Photosynthetically Active Radiation (PAR), spectrum, humidity, temperature, CO2, atmospheric pressure, and has an optional input for leaf temperature to provide Vapor Pressure Deficit (VPD) measurements.
RAYN Multi-Sensor
The RMS reports photosynthetically active radiation (PAR 400–700) from 0–4000.0 photosynthetic photon flux density (PPFD) (μmol/s/m2) to a connected RAYN Touch controller over a wireless EnOcean® signal. Sensor reports are logged by the RAYN Touch controller or the Syrcadia software for graphical trending over time and data export.
The sensor is powered by an integral solar panel; batteries are not required for everyday use due to the advanced solar energy harvesting, but are available for longer data transmission in dark environments. After installation, the sensor will operate with the exposure to light as little as 10 μmol for five minutes. The RAYN Multi-Sensor can operate over 48 hours in darkness from maximum charge levels. An optional battery assist can be fitted when the sensor will be in a dark environment for longer periods.
The RAYN Multi-Sensor is enclosed in an ingress protectiion IP67-rated aspirated enclosure. The local display allows for direct readout of the measured data.
