About Collection Devices

You can select from a variety of sensors and interfaces to collect data while running the Vernier DataQuest™ application with TI‑Nspire™ software.

Multi-Channel Sensor Interfaces

Multi-channel sensor interfaces let you connect more than one sensor at a time.

 

Sensor Interface

Description

Texas Instruments TI‑Nspire™ Lab Cradle

This sensor can be used with a handheld, a computer, or as a stand-alone sensor.

The sensor interface allows you to connect and use one to five sensors at the same time. It can be used in the lab or at a remote collection location.

The Lab Cradle supports two digital sensors and three analog sensors.

The Lab Cradle also supports high-sample data collection sensors, such as a hand-grip heart rate or a blood pressure monitor.

After using the Lab Cradle as a remote sensor, you can download data to either a handheld or computer.

Single-Channel Sensor Interfaces

Single-channel sensor interfaces can only connect to one sensor at a time. These sensors have either a mini-USB connector for a handheld or a standard USB connector for a computer. For a complete list of compatible sensors, see Compatible Sensors.

 

Sensor Interface

Description

Vernier EasyLink®

This sensor interface is used with handhelds. It has a mini-USB connector so it can be plugged directly into the handheld.

Connect sensors to Vernier EasyLink® to:

• Measure barometric pressure.
• Measure the salinity of a solution.
• Investigate the relationship between pressure and volume (Boyles’ Law).

Vernier Go!Link®

This sensor interface is used with computers. It has a standard connector so it can be plugged into a Windows® or Mac® computer.

Connect sensors to Vernier GoLink® to:

• Measure the acidity or alkalinity of a solution.
• Monitor greenhouse gases.
• Measure sound level in decibels.

Types of Sensors

• Analog sensors. Temperature, light, pH, and voltage sensors are analog sensors and require a sensor interface.
• Digital sensors. Photogates, radiation monitors, and drop counters are digital sensors. These sensors can only be used with the TI‑Nspire™ Lab Cradle.
• Direct-connect USB sensors. These sensors connect directly to a handheld or computer and do not require a sensor interface.

Sensors for Handhelds

The following lists some sensors you can use with a handheld.

 

Sensor

Description

Texas Instruments CBR 2™

This analog sensor connects directly to TI‑Nspire™ handhelds through the mini-USB port. It is used to explore and graph motion.

This sensor automatically launches the Vernier DataQuest™ application when you connect it to a handheld. Data collection begins when you select the Motion Match function.

This sensor collects up to 200 samples per second.

Use this sensor to:

• Measure position and speed of a person or object.
• Measure the acceleration of an object.

Vernier EasyTemp® temperature sensor

This analog sensor connects directly to TI‑Nspire™ handhelds through the mini-USB port and is used to collect temperature ranges. You can design experiments to:

• Collect weather data.
• Record temperature changes due to chemical reactions.
• Perform heat fusion studies.

Sensors for Computers

The following table lists some sensors you can use with a computer.

Sensor

Description

Vernier Go!Temp® temperature sensor

This analog sensor connects to the computer’s USB port and is used to collect temperature ranges.

You can use this sensor to:

• Collect weather data.
• Record temperature changes due to chemical reactions.
• Perform heat fusion studies.

Vernier Go!Motion® motion detector

This analog sensor connects to the computer’s USB port and is used to measure acceleration, speed, and velocity.

Use this sensor to:

• Measure position and speed of a person or object.
• Measure the acceleration of an object.
