are factory-determined coefficients
for each flow sensor.
Infrared temperature sensor
Leaf temperature (°C) is computed as a function of the
reference temperature and the IRT sensor response
9-19
where V
leaf
is the voltage from the IRT target, T
ref
is the
reference temperature and a
tl
to g
tl
are factory coef-
ficients.
PAR sensor
Photosynthetically active radiation (µmol m
-2
s
-1
) is com-
puted from a factory-calibrated photodiode response.
9-20
where V
par
is the voltage measured from the sensor,
Z
quantum
is a user-settable offset for when no light reaches
the sensor, and Q
coeff
is a factory calibration with units of
