4. Sensor Installation
4.1 Soil Sensor Installation
The sensor can be oriented in any direction. However, orienting the flat side perpendicular to
the surface of the soil will minimize effects on downward water movement. There are two basic
methods to accomplish a high-quality installation.
4.1.1 Horizontal Installation
1. Excavate a hole or trench a few centimeters deeper than the depth at which the sensor is to
be installed.
2. At the installation depth, shave off some soil from the vertical soil surface exposing
undisturbed soil.
3. Insert the sensor into the undisturbed soil surface until the entire sensor is inserted. The tip of
each prong has been sharpened to make it easier to push the sensor into the soil. Be careful with
the sharp tips!
Note: If there is difficulty inserting the sensor, loosen or wet the soil.

4. Put the motherboard back and restore
everything in its due position.
3. Pull out the motherboard, insert and lock
the wires accordingly (see the label on the
motherboard or following picture).

4. Backfill the trench taking care to pack the soil back to natural bulk density around the sensor
body.
4.1.2 Vertical Installation
1. Drill a 3-in hole to the depth at which the sensor is to be installed.
2. Insert the sensor into the undisturbed soil at the bottom of the drilled hole using a hand or any
other implement that will guide the sensor into the soil at the bottom of the hole.
3. After inserting the sensor, backfill the hole, and take care to pack the soil back to natural bulk
density while not damaging the overmolding of the sensor and the sensor cable in the process.
Installation Note:
Abnormal data may show up if sensor prongs are exposed in the air.
It is possible to get sticks, bark, roots or other material stuck between the sensor prongs,
which will severely affect the sensor data readings. Any air gaps or excessive soil compaction
around the sensor can also influence the readings.
Do not install the sensor adjacent to large metal objects.
Be careful when inserting the sensor into dense soil, as the prongs will break if excessive
sideways force is used.
When installing the sensor in a lightning prone area, please check your lightning protection.
When removing the sensor from the soil, do not pull it out of the soil by the cable. Doing so
may break internal connections and make the sensor unusable.

4.2 EM500 Installation
Ensure the location of EM500 is within the communication range of LoRaWAN gateway.
4.2.1 Wall Mounting
1. Attach the mounting bracket to the wall and drill. (Around 16mm)
Note: The connecting line of two holes must be a horizontal line.
2. Mount the device on the wall.
4.2.2 Pole Mounting
1. Loosen the hose clamp by turning the locking mechanism counter-clockwise.
2. Straighten out the hose clamp and slide it through the rectangular holes in the mounting
bracket, wrap the hose clamp around the pole.
3. Use a screwdriver to tighten the locking mechanism by turning it clockwise.
4.2.3 DIN Rail Mounting
Use 2 pieces of M3 × 6 flat head Phillips screws to fix the DIN rail to the device, and then hang
the DIN rail on the mounting bracket. It is necessary to choose a standard bracket.
