Physical Interfaces
Figure 3 below illustrates the customer accessible interfaces for the Agricultural Sensor. All
models share the same layout.
Legend:
1A = Input 2+ (RES)
1B = Input 1+ (RES)
2A = Input 2-
2B = Input 1-
3A = Input 3 (Thermistor 1)*
3B = Moisture 1 (Watermark 1)*
4A = Input 3 (Thermistor 1)*
4B = Moisture 1 (Watermark 1)*
5A = Input 4 (Thermistor 2)*
5B = Moisture 2 (Watermark 2)*
6A = Input 4 (Thermistor 2)*
6B = Moisture 2 (Watermark 2)*
7A = GND (RES)
7B = Power (RES)
RES = Reserved pins for Soil Surface Mount Module Only
*NOTE there is no polarity on either the Thermistors or Watermarks that are shipped in the kit
with the Elevated Pole Module. The wires can be installed into the terminal block pins either
way.
