STEM education and motivate self-directed learning.
Quality and Effectiveness: Vernier’s LabQuest 2 is an openended
handheld tool that can be used to collect sensor data at a
rate of 100,000 samples per second. This 12-ounce touch tablet
integrates graphing and analysis software for data gathering and
visualization in STEM subjects. Its rechargeable lithium-ion battery
lasts about six hours for stand-alone work before it must be recharged
with the supplied power adapter. With two digital ports, a USB port,
and three analog ports, the LabQuest 2 can collect data from dozens
of connected sensors or a USB flash drive. The unit also has a builtin
microphone, stopwatch, calculator and GPS, plus an 800 MHz
application processor for data gathering.
Ease of Use: Preparing the LabQuest 2 for use couldn’t be simpler.
The LabQuest 2 comes with five built-in sensors for data acquisition. It
features 3 Accelerometers (X, Y, and Z), plus sensors for Temperature
and Light. The unit’s builtin

pixel color touch screen,
merely 40 MB RAM
for storage, and lacks Bluetooth and Wi-Fi capabilities. LabQuest 2, on
the other hand, boasts 200 MB of RAM, and almost twice the display
resolution. LabQuest 2 also features support for Vernier’s Connected
Science System, allowing users to share data using the built-in Data Share
software by connecting the handheld to any device (including iOS and
Android) with a compatible Web browser.
