The fencing of the area and the stainless steel pole was managed and implemented by members of the Irrigation Department. Figure 2 shows the pre-installation situation of the fenced area where the observation system was installed. The installation of automatic weather station equipment for Zaung Tu Weir was started at 9:00am in the morning.

The installation started by assembling the mounting of solar panel to be attached to the steel pole as shown in left image of Figure 3. Simultaneously, another group was putting together the weather sensor assembly (weather sensor and included pole holding the sensor) as shown in right image of Figure 3. Figure 4 shows the attachment of the solar panel to the mount support being done by the members of installation team. Left image of Figure 5 shows the attachment enclosure holding the data logger, modem, battery, and other appurtenances.
