Installation Notes

Problems and Considerations (May 2020)

• Sensor Height – mount at current height (20’).
  • Cantilever arm must be level and static.

• RSSI issues – receiver is nearby, but leaf cover may be blocking line of sight.
  • Could try to get antenna out over river further or up higher.
  • Could mount transmitter and sensor separately.

• Safety Issues – location has a steep (~10’) drop off into the river.
  • Design must take into account river safety and ease of access of transmitter.

• Access issues – location is immediately adjacent to road, but in a precarious spot at edge of bank.
  • If transmitter is mounted separate from sensor, both will need to still be accessible for battery changes, maintenance.

• Sensing Cone Issues – the cone of detection is very wide at water surface.
  • Any interfering branches may need to be removed.
  • Sensor should be mounted out over the river as far as it is now or farther.
