Requirement Identifier C_M_F_solarRadiationSensing
Name: Solar Radiation Sensor
Text: The Station Module of the PlanCTTM
System shall provide information about the daily
sunshine duration. For this purpose a sensor with capability of
measuring solar radiation (in W/m2) is needed.
Required technical parameters:
- Maximal mass: < 200g
- Stock temperature: -45 Grad Celsius .. +125 Grad
Celsius
- Operating temperature: -35 Grad Celsius .. +85 Grad
Celsius
- Intesity measurement range: 2 [W/m2].. 1.400
[W/m2]
- Spectral range: 380 nm .. 2.800 nm
- Standard deviation error: max 5 %
- Accuracy: standard deviation error + max. 2 % of the
measured value
- Resolution (in case of digitalized output): min. 10
bit
Rationale: Solar radiation transmitted through the
Earth's atmosphere has two domains of incoming radiant fluxes
which have a significant impact on plants: the
photosynthetically active (0.38-0.7 nm) and the near infrared
one (0.7-2.8 nm). The solar radiation intensity has to be
examined in various wavelenghts, because the cloud absorption
abnormality affects the plant groving and the formation of
diseases differently. Moreover, summarizing the daily sunshine
durations can give an accurate estimate of the actual evolution
state of different plant cultures.

Source: In viticulture applications sunshine duration is a key indicator of
the expected wine quality. This is a commonly required parameter by the end-users.
