Photosynthetically Active Radiation (PAR)
Smart Sensor (Part # S-LIA-M003)
The Photosynthetically Active Radiation (PAR) smart sensor is designed
®
to work with the HOBO
Weather Station logger. The smart sensor has a
plug-in modular connector that allows it to be added easily to a HOBO
Weather Station. All calibration parameters are stored inside the smart
sensor, which automatically communicates configuration information to
the logger without any programming, calibration, or extensive user setup.

This product meets CE specification EN61326 criterion C for ESD, criterion
C for Radiated Immunity, criterion B for Fast Transient, criterion A for
Conducted Immunity, and criterion A for Power Frequency Magnetic Fields.
To minimize measurement errors due to ambient RF, use the shortest
possible probe cable length and keep the probe cable as far as possible
from other cables.

- Page 2 PAR Smart Sensor Figure 1: PAR Smart Sensor Typical Quantum Response Note: The PAR smart sensor is designed to detect photons between 400-700 nm in wavelength. Ideally the sensor would count photons with equal efficiency between 400-700 nm and no photons would be counted outside this range.
- Page 3 PAR Smart Sensor 5. Mount the light sensor bracket on the mast with the two U-bolt assemblies, mounting it high enough on the mast to avoid the possibility of shading the light sensor. Note: If you mount the light sensor above eye level, it is recommended that you use a step ladder or other secure platform when leveling the sensor so that you can clearly view the light sensor level (Onset Part # M- LLA).
- Page 4 If a port is not available, use a 1-to-2 adaptor (Part # S-ADAPT), which allows you to plug two sensors into one port. The next time the HOBO Weather Station is launched it will automatically detect the new sensor. Note that the HOBO Weather Station supports a maximum of 15 data channels;...
