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.
