How to Calibrate GroLab™ SoilBot Moisture Sensors

GroLab™ system has several distinct modules, sensors and devices. One of those modules is GroLab™ SoilBot.
SoilBot supports several sensors and flood detectors, proving all the tools to fully monitor the plants substrate.
On today’s GroLab™ Tips & Tricks post we will explain how to calibrate SoilBot moisture sensors. Those sensors constantly analyze the amount of water in the substrate, from 0% (dry) to 100% (wet).

Calibrating a SoilBot Moisture Sensor

After installing the GroLab™ modules and GroLab™ Software, one of the first things to do is to configure devices and sensors that you connected to the modules. For the SoilBot’s moisture sensors, one of the tasks is to calibrate them.
To calibrate SoilBot’s moisture sensor follow this steps:

1 – Open GroLab™ Software (A), authenticate (B) and proceed to the main menu (C);
Instructions to open GroLab™ Software: A-Open GroLab™ Software from desktop shortcut; B-Insert credentials and click to proceed; C-Click on "Go To Grow" button; Wait loading operation.

2 – Access modules section (A), then select SoilBot tab (B), choose the SoilBot (that has the connected moisture sensor to calibrate) (C) and then click on the desired moisture sensor (D);
Instructions to access SoilBot moisture sensor configuration wizard: A-With GroLab™ Software open on the main menu click on the modules section button from left panel; B-Select SoilBots tab on the top of modules menu; C-Choose the desired SoilBot from right side panel; D-Click on the desired moisture sensor.

3 – If the moisture sensor is already configured skip to step 4. If not, set his type (A, B & C) and name (D);
Instructions to configure SoilBot moisture sensor: A-With GroLab™ Software open inside devices/sensors configuration wizard, click on the icon representing current type (if not configured yet it shows a not connected icon); B-Choose the desired type, in this case moisture sensor; C-Click to apply; D-Set a name to the sensor.

4 – Click on “Calibrate Sensor” button to access the calibration wizard (A);
Instructions to open moisture sensor calibration wizard: A-With GroLab™ Software open inside devices/sensors configuration wizard, click on the "Calibrate Sensor" button; Then the calibration wizard will appear.

5 – Before doing this step clean the moisture sensor with a dry clean cloth. Then leave it in open air and wait at least 1 minute for the sensor value to stabilize. After that, on the GroLab™ Software, press the “Go” button corresponding to the moisture min (A), wait calibration to finish and then press ok button (B);
Instructions to calibrate moisture sensor low point: A-With GroLab™ Software open inside moisture sensor calibration wizard, click on "Go" Button on the left side inside the "Moisture Min" panel; Wait the calibration operation to end; B-Click "ok" button when the success message prompt appears.

6 – Before doing this step insert the sensor on a cup of water or on the desired substrate fully saturated. Then wait at least 1 minute for the sensor value to stabilize. After that, on the GroLab™ Software, press the “Go” button corresponding to the moisture max (A), wait calibration to finish and then press ok button (B);
Instructions to calibrate moisture sensor high point: A-With GroLab™ Software open inside moisture sensor calibration wizard, click on "Go" Button inside the "Moisture Max" panel; Wait the calibration operation to end; B-Click "ok" button when the success message prompt appears.

7 – Your moisture sensor is now calibrated. You can insert it on the desired substrate to start monitoring the moisture level. Feel free to repeat the calibration at any time. Now click on the “Save and Close” button (A) and then on sensor configuration wizard click on “Save and Close” button (B).
Instructions to save and close moisture sensor calibration wizard: A-With GroLab™ Software open inside moisture sensor calibration wizard, click on the green button to apply configuration and close the wizard; B-It will return to the devices/sensors configuration wizard and click on the green button to save and close.

After calibrating the desired moisture sensors it is time to use them. GroLab™ system provides several options to use those sensors, like auto-feeding based on substrate’s moisture and shutdown the irrigation in case of flood.
