WebFeb 12, 2024 · CBR™ 2 motion sensor – The CBR™ 2 is TI’s answer to an easy, affordable data collection device! Designed for teachers who want their students to collect and analyze real-world motion data, such as distance, velocity and acceleration. The CBR™ 2 system is our answer to an easy, affordable data-collection device. WebPassive sensors "detect" changes in their surrounding fields and transform these changes into a voltage e.g. change in pressure, temperature or brigthness. Active sensors don't produce voltage, but change their impedance depending on their surrounding fields and therefore the current flowing through them.
