Description
The Observant field unit measures rainfall from the Davis tipping bucket rain gauge by counting pulses from the rain gauge. The field unit uses one of its port inputs to count these pulses and Observant Global converts this to a measurement of rainfall over time.
As part of an Observant system, a tipping bucket rain gauge will show rainfall totals for:
- Today.
- Last 7 days.
- This month.
- This Year
For soil moisture applications, rain gauge data can also be integrated into Crop Manager in Global.
Supported hardware
Manufacturer: Davis
Model: Rain Collector II

Typical Applications
Rainfall Monitoring
Installation
- Install the rain gauge according to the manual.
- Make a note of the rain gauge version to determine the wire colours. See the label on the side of the tipping spoon to verify version.
- Remove the existing connector from the cable.
- Strip the required conductors as above to leave 5mm exposed conductor. Trim back the remaining wires; they are unused.
- For Version A, connect the red and green conductors to an available input of a C3, ignore any other wire colours.
- Red—Input Ports 1 (default), 2, 3, or 4
- Green—Ground
- For Version B, connect the black and red conductors to an available input of a C3, ignore any other wire colours.
- Red—Input Ports 1 (default), 2, 3, or 4
- Black—Ground
The maximum wire run should be no more than 200m, taking into account wiring gauge and environmental protection.
