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.
|
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.
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.
Texas Instruments CBR 2™
|
This analog sensor connects directly to TI-Nspire™ CX II 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™ CX II handhelds through the mini-USB port and is used to collect temperature ranges. You can design experiments to:
|
•
|
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.
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:
|
•
|
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. |
|
