Rain Totals on Web UI
This page supports settings such as:
(1) Choose traditional or piezoelectric rain gauge data to be
uploaded to the WU server, as only one rain gauge data can be
accepted when you have both our haptic rain gauge and tipping
bucket type rain gauge.
(2) Rainfall calibration
(3) Rain reset time for Daily Rain/Weekly Rain/Rainfall Season
(4) For Piezo Rain1~5 Gain calibration
Piezoelectric rain gauge working principle: raindrops fall on the
sensor's surface so that the monitoring panel produces small
mechanical vibration, the vibration of the mechanical stress, and
the sensor produces a voltage difference corresponding to the
amount of rainfall.
In practice, the measurement of precipitation by piezoelectric
rain gauges is influenced by environmental factors such as wind,
terrain, and debris. In the case of large rainfall intensity, rainfall
intensity can be measured by the piezoelectric rain gauge, but the
raindrops landing may have two impacts on the monitoring panel
so that the measured rainfall value is larger; for minimal rainfall
intensity, due to the vertical momentum is too small, so that the
measured rainfall value is small. Therefore, it is necessary to
calibrate the piezoelectric sensors for different rainfall intensities
depending on the environment in which they are located.
