the Pearl Modbus Advance Digital Integrated Sensor Module (Temperature/Humidity/C02) Installation Diagram

Here are Different Com 1 & Power Locations on the Various Modules 

For mounting, simply use the zip tie to hang the Sensor. This is the most common method for indoor installations. The sensor should hang just above the plant level in a central location of the greenhouse

Note:  When running sensor cables be sure to keep them away from interference sources, including high voltage power lines, inverters, motor controllers, and mercury arc or sodium lamp circuits, VFDs.

Junction Box

If it becomes necessary to extend the sensor wire, be sure to use a Link4 junction box, or an equivalent NEMA 4 sealed box. Water or fertilizer infiltration could cause unstable sensor readings. Please make sure to connect the shielded wire to the ground as shown in the diagram above to avoid interferences.

Once you have Installed your Sensor, next you will need to get the sensor to read on the Pearl Controller.

you would need to Scan and detect your Senso

After you have scanned your Sensor Module Board and have confirmed its Status is OK and is GOOD  in Expansion settings

go to Setup Inputs and Map your InT (Inside Temperature) In Hum (Inside Humidity) and C02 to Sns Module (Sensor Module)
