Texas Instruments introduced in 1994 with the Calculator-Based Laboratory™ System (CBL™) a portable and versatile data collection device for math and science. A wide variety of sensors, such as a Motion Detector, Dual-Range Force Sensor, pH system, Colorimeter, and Barometer, can be connected to the CBL interface. In this configuration the battery powered CBL could be uses a stand-alone data logger even outside the classroom for experiments. An additional link cable connects the CBL to one of TI’s graphing calculators such as the a TI-73, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-85, TI-86, TI-89, TI-92, TI-92 Plus and Voyage 200. Data is now collected under program control of the calculator and the systems is capable to analyze real-world data as a low-cost alternative to using computers. The hardware of the CBL System makes use of a powerful H8/3813 microcontroller connected to a fast 10-bit Analog-Digital converter, a 8k*8 RAM and a LC-Display for convenient readout. The microcontroller is based on a H8/300L Low-Power 8-bit CPU and integrates the LCD-drivers, 0.5kByte RAM for internal storage and 24kByte ROM for the program. The CBL system accepts three analog inputs, an ultrasonic motion detector input to connect the Calculator-Based Ranger CBR, a digital input channel with 4 discrete bits, and a digital output channel with 4 bits. The sampling rate is adjustable between 10,000 samples per second to one sample every 4 hours. Due to the own microcontroller and memory the CBL could be disconnected from the graphing calculator and act as a stand-alone device. The software inside the CBL is powerful and includes: • Compute first and second derivatives on collected data. • Compute minimum, maximum, mean, and standard deviation statistics values on collected data. • Record absolute or relative time as data is collected. • Sophisticated data smoothing algorithms built in. • View data being collected on all active channels via the Channel View function (CH VIEW key). • 6 different triggering options including sample on TRIGGER keypress. The CBL System comes packaged with the original CBL interface, a temperature probe, light probe, voltage probe, experiment workbook, user's guidebook, batteries, and carrying case. Vernier Software of Portland, Oregon manufactures a lot of CBL compatible sensors,.
