The CBL System
What Is the CBL?
The Calculator-Based Laboratory Systemé (CBLé) is a portable,
handheld, battery-operated, data-collection device for collecting “real-
world” data. The data collected with the CBL can then be retrieved by a
calculator for further analysis. With the CBL system and appropriate
sensors, you can measure motion, temperature, light, sound, pH, force,
and more.
This Is What You Get

CBL
TI Probes
TI provides three probes to get you started with the CBL.
¦ Temperature Probe: This probe uses a thermistor to measure
temperature.
¦ Light Probe: This probe uses a phototransistor to measure light
intensity.
¦ Voltage Probe: This generic probe measures voltage between ±10
Volts (
CH1
and
CH2
only).
Note: Appendix A contains detailed technical information about these
probes, pinout data, and other information to assist you in making your
own probes.
Additional sensors and probes, used with CBL through optional
adapters, can be purchased from other vendors.
