Providing Power

Power for LabQuest Mini is supplied by the USB port of the computer or Chromebook to which it is connected. LabQuest Mini does not need batteries or an external AC power supply.

In rare cases, underpowered computer USB ports can prevent your LabQuest Mini from working as designed. In those situations, we recommend using a powered USB hub with your LabQuest Mini.

Connecting Sensors

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.
