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 is used with handhelds, computers, or as a stand-alone sensor. This 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 monitor or a blood pressure monitor. When used as a remote sensor, you can download data to either a handheld or a computer. For more information, see the TI-Nspire™ Lab Cradle Guidebook. 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 use with a handheld or a standard USB connector for use with a computer. For a complete list of compatible sensors, see Compatible Sensors. Sensor Interface Vernier EasyLink® Description 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). 6 Getting Started
