Once the sensors have been connected, they must be configured. In the web interface, navigate to the Temperature
Sensors menu. Located at the bottom of the page you will see "1 unconfigured sensors found on this device" followed by
the unconfigured sensor showing an ADD button (any one-wire sensor can be used in this way).
Alternately, it is possible to pre-add the sensors using the ID
found on the sensors sold by FlexSCADA and its re-
sellers. All one-wire sensors will have a unique ID. FlexSCADA one-wire sensors have been labeled with this pre-
existing ID for ease of use.
The Q5 supports 1-wire sensors. The below diagram shows how to connect and provide a 1-wire sensor with power
and data communication. The Q5 supports up to 64 sensors, each sharing the same 3 wires.
Adopt unconfigured
temp sensor.
Manually add temp sensor.
(Sensor ID found on sensor
wire shown right.)
The below example shows a newly added temp sensor, along with the options to name the sensor and choose which
metrics to log or add to the dashboard.
The display units can be modified in the
Device Options menu.
Show/Hide sensor options.
ID of the sensor, this can be updated
if a sensor needs to be replaced.
Sensor Label - this label is used on the
dashboard and in the graphing.
Detailed sensor description. (optional)
Select what metrics you wish to graph or
display on the dashboard. For min, max
and average time period see Section 1.8 -
Measurement Interval.
Tags help in selecting datasets when graphing. An example might be "greenhouse 1"
allowing an easy way to select sensors belonging to that greenhouse.
Delete this sensor.
New temp sensor displayed
on the dashboard.
To attach additional one-wire sensors a standard wiring
bus will be required, as the terminals are not physically
capable of holding more than a few sensors.
Each one-wire sensors has a unique digital ID that makes
it possible to view its value without interfering with the
other sensors.
