Combining Motion and Analog Measurements

Download (720 KB)

Using the 720281 Frequency Module to capture and convert incoming pulses from an encoder or Hall Effect sensor, it's easy to combine motion measurements such as distance, velocity, or RPM together with other motion sesnors such as accelerometers and analog inputs such as current or voltage measurements. In this application note lear about the many functions of the Frequency Module in combination with the 701275 Accelerometer Input Module.
