How to connect a data logger / controller
The PRONAMIC PCB has a terminal strip with four connection (two outlets). The two outlets are marked as 1-2 and 3-4. The outlet 1-2 is connected by a reed switch and the state is Normally Closed (NC). The outlet 3-4 is connected by another reed switch and the state is Normally Open (NO). When the tipping bucket tips, then the reed switches changes state.
See the following guide for connecting the PCB to a IoT Device/Microcontroller
- Connect your IoT Device/Microcontroller with wires to the following screw terminals:
Screw terminal 1-2 (Red arrow in Figure 1) if the desired state of the reed switch is
- Normally Closed (NC).
- Screw terminal 3-4 (Green arrow in Figure 1) if the desired state of the reed switch is Normally Open (NO).
- Configure the software to add the calibration value (either; .1 – 0.2 – 0.25 – 0.5 – 1 mm) each time the tipping bucket tips, and the reed switch changes state from open to closed or closed to open.
OBS: Remember to check if your IoT controller has a built-in pull-up resister.
Is there a data-logger / controller included?
What are PRONAMIC delivering to a setup?
We at PRONAMIC supplies the hardware of a high quality rain gauge. You as the business customer is supplying the data logger / controller / sensor node which communicates with your entire system.
Does the Rain Gauge need a power supply?
PCB 9602 = Normally Open or Normally Closed.
PCB 9601 = Normally Open.
Safety feature on PCB 9602 - TVS diodes
See more information here: Professional rain and precipitation sensor
How is the calibration value in calculated?
This example is for the calibration: 0.2mm/tip
Pronamic Professional funnel orriface: 200cm2
200cm2 = 0.02m2
0.2mm pr. tip.
0.2mm x 0.02m2 = 0.004 liter
0.004 liter = 4ml – thus the calibration is 4ml/tip
