Installing a Soil Moisture Node
Our SDI-12 soil moisture node is plug-and-play with all Aquacheck soil moisture probes. No configuration is required.
Installation steps:
-
Be sure to first connect the soil moisture probe before powering up the unit.
-
Connect the soil moisture probe to the node by running the cable through the gland. Connect the coloured wires as follows:
-
Gnd = Black wire​
-
Data = Blue wire
-
Power = Brown wire
-
(Note to electricians - remember this is an electronic device and not a 3-phase heavy current motor. Please don't over tighten the electrical connectors ;-)
-
-
Do be sure to tighten the outside gland nut so that it secures the cable and acts as a strain-relief for the connectors.​
-
Power up the unit by inserting four new size C batteries of a reputable brand. Be sure to observe the correct polarity. On initial boot you will see two long LED flashes. (This will be followed by 4 short flashes when the device joins the LoRa network.)
​
Mounting your device in the field:
-
If you need to mount your device on a frame/pole/backing board please do not drill new holes in the enclosure as this will compromise moisture ingress. Instead please use the existing holes on the four outside corners.
-
Make sure the gland is facing downwards to avoid moisture ingress.
