PEARL - Soil Moisture Sensor Installation on 5 Input Module

The Pearl Soil Moisture Sensor would be wired to your 5 Input Module in the following way:

The White Wire of Temperature Probe would go to 3V on bottom of Module

The Red Wire would go to the (+) of the Input you are going to use for the Temp Probe

The Shield Metal Wire would go to the (-) of the Input you are going to use for the Temp Probe

     note:  we recommend using 22 Gauge 2 Twisted Shielded Pair Wire when extended sensor wire runs.

Once wired you would have to map sensor to this module board

(for example let say this Module is board 4, and you have 5 Soil Moisture Sensors you want to have in separate benches in greenhouse for independent  Volumetric Water Content  reporting of an area)

you would map it in sensor mapping:

hit Enter button, go into System Setup, then Setup Inputs, and you would hit enter to highlight the editing field and scroll down to change Soil 1,2,3,4,5 to be In Bd4 Ch1,2,3,4,5 

The key is knowing both when and how much to water!

Maintaining a healthy soil moisture and water balance is essential for producing high quality plants.  

Under-watered plants suffer from nutrient deficiencies, stunting and wilting.

Over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle.         

Extreme over-watering will suffocate the plant and lead to root death.

 The Soil Sensor

Measures Volumetric Water Content (VWC) of soil

Capacitance-type sensor responds immediately to changes in soil moisture content for better irrigation decisions

Calibrated for mineral soils or soilless media

Installs easily into 3/4 in (1.9 cm) hole

Install permanently or use to take spot measurements

Can be read with the Pearl Environmental Controller.

You can connect multiple Soil sensors per iGrow Controller depending on the quantity of Input Module Outputs you have available, and you can always add more 5 Input Modules.
