Quick Start Guide for Moisture Sensor
1Introduction
The purpose of this Quick Start Guide is to briefly explain what a moisture sensor is and how
it can be set up and used. The sensors function using a Smart Switch in combination with
the Ridder HortiMaX-Go!.
1.1 Introduction to Moisture Sensor
Ridder uses sensors that measure the moisture content, the Electric Conductivity (EC) and
the temperature of the plants' growing medium (or substrate) in order to optimize your
cultivation process. Ridder works with the TEROS-12 (CateC) sensor. You can connect
multiple sensors to the Ridder Moisture Smart Switch.
1.2 Use
The Ridder Moisture Sensor can be connected to the following Ridder process computers:
CX500, MultiMa and HortiMaX-Go!. Only operate the equipment if you are familiar with how
these process computers work.
This Quick Start Guide describes the use of moisture sensors in combination with the
HortiMaX-Go!. The data that the sensor collects is combined with data from other sensors.
This gives you an accurate picture of the current conditions in your greenhouse and allows
you to adjust your climate and irrigation controls accordingly.
1.3 Additional documentation
You can read more about the installation and use of moisture sensors in the following
documents:
−HortiMaX-Go! Installation Manual
−HortiMaX-Go! User Manual
−CX500 Dealer Manual
−Moisture Smart Switch Insert
−OEM (Original Equipment Manufacturer) documentation provided.

2General
This chapter provides more information on how to use the moisture sensors and how to
display the measurement data.
2.1 Moisture sensor with the HortiMaX-Go!
The moisture sensor sends the measurement data via the MTV-Go! to the HortiMaX-Go!.
This data can be displayed using one of the control panel units shown below.
Control panel cabinet with HortiMaX-Go!
Control panel cabinet with a built-in
HortiMaX-Go! panel PC, running the
controller software.
HortiMaX-Go!
Individual HortiMaX-Go! panel PC running
the controller software.

2.2 Screen layout of HortiMaX-Go!
The main screen of the HortiMaX-Go! is the home screen. The home screen displays a
number of fixed elements, such as the tiles, the top bar and the right sidebar.
The screenshot below shows an example of the home screen. What the home screen
looks like exactly on your system depends on your configuration.
1. Top bar, left-hand side, showing the breadcrumb trail
2. Tile header
3. Tile body, showing specific information
4. Top bar, right-hand side, providing direct access to manual control, valves and
alarms
5. Right sidebar
2.3 Setting up sensor to display moisture data
You can find the moisture
sensors after the valves
in the valves overview:
This screen shows the
EC [mS/cm] and the
moisture content [%]
measured by each
sensor.

To set the delay time for
irrigation after a moisture
content start is triggered,
proceed as follows:
Select the moisture
sensor:
Select general settings:
Set the delay time.
On the moisture sensor
screen, tap:
This enables you to set
the alarm limits for the
moisture content, the EC
and the temperature of
the substrate.
If necessary, set a delay
time for the alarms.
Go to the settings for
the valve groups.
Here you enter the start
conditions for each
recipe.
Step 1: Set delay time for irrigation
Step 2: Set the alarm limits and the delay time for the alarms.
Step 3: Enter the start conditions for each irrigation recipe.
A recipe is a combination of values at which irrigation should start.

2.4 Displaying the measurements
To display the
measurement data, tap
the magnifying glass icon:
You will now see the
measured values for the
moisture content, the EC
and the temperature of
the substrate.
Go to the moisture screen
and tap the icon below:
You will now see the
averages, and the
minimum and maximum
values over a 24-hour
period.
To compare data over a
longer period of time in a
graph, you can use the
icon below to generate a
graph from the moisture
screen:
Step 1: Tap the magnifying glass icon on the moisture sensor screen.
Step 2: To view the historical data for the last 24 hours, proceed as follows:
Step 3: To view these values over a longer period of time, proceed as follows:

On the moisture screen,
select the purple icon:
Tap the magnifying glass
icon:
You will see the current
measurements and the
type and status of the
sensor.
After selecting the valve
group, navigate the
following path:
You can see when and at
which moisture content
level an irrigation cycle
started, and also which
sensor triggered the
irrigation cycle.
Step 4: To see a more detailed overview of the current situation, proceed as follows:
Step 5: To check when an irrigation cycle started and which sensor triggered
irrigation, proceed as follows:

From the valve
group screen,
navigate the
following path:
You can now see
which type of start
triggered the last
cycle. In this
example, the type of
start is Moisture
content.
Step 6: To check which type of start triggered the last irrigation cycle, proceed as
follows:
The moisture sensor can only be used to start an irrigation cycle. A substrate
moisture sensor cannot prevent an irrigation cycle from starting. This means
that if you have set a pause time and the moisture content is still too high
after the pause time has elapsed, the irrigation cycle will start regardless of
the measured moisture content. If the substrate is too dry before the pause
time has elapsed, the irrigation cycle will start as set.
Tip: Ridder offers a wide range of sensors. These can be operated in a
similarly simple manner, enabling you to create the ideal growing environment
for your crops. For more information, please contact your local dealer or go to
