Connecting Sensors
LabQuest Mini supports two types of sensors—analog and digital. Connect
sensors to the appropriate port on your LabQuest Mini.
Analog Sensors
Examples of analog sensors are temperature probes, pH sensors, and force sensors.
Up to three analog sensors can be connected to LabQuest Mini. The three ports for
analog sensors (CH 1–CH 3) are located on the top side of the unit. These ports
accept British Telecom-style plugs with a right-hand connector.
Digital Sensors
Examples of digital sensors include motion detectors, photogates, and
rotary motion sensors. Up to two digital sensors can be connected to
LabQuest Mini. The two ports for digital sensors (DIG 1 and DIG 2) are located
on the bottom side of the unit. These ports accept British Telecom-style plugs with
a left-hand connector.
Note: Most sensors are automatically identified allowing the software to set up a
default experiment. If you are using a sensor that does not auto-ID, you will need
to manually identify the sensor in the software when supported.

Care and Maintenance
Water Resistance
LabQuest Mini is not water resistant and should never be immersed in water. If
water gets in the device, immediately disconnect all sensors and cables. Allow the
unit to dry thoroughly before using it again. Do not attempt to dry it using an
external heat source.
Storage
Do not store LabQuest Mini in a chemical closet or in areas of concentrated
chemical gasses.
How the Interface Works
The LabQuest Mini interface is more than just a physical adapter between two
different connectors. It is hardware that allows Vernier sensors to interact with
computers and Chromebooks. LabQuest Mini contains dedicated electronics for
precise sampling of sensor events. LabQuest Mini timestamps these events so
measurements from multiple sensors can be analyzed simultaneously. To allow
data to flow smoothly, LabQuest Mini manages the communication link between
the sensors and the computing platform.
