Sometimes you need to measure how fast a wheel is going on your GM 2/3/8/9 gear motor. Here's your solution!
Get two GMWW02 encoders in one package. Now shipping the new WW-02 version.
Here's a really cool quadrature encoder and motor driver for the GM17 Gear motor designed by the micro-specialists at Didel.
This quadrature encoder board is designed to hold two infrared reflectance sensors inside the hub of a Pololu 42×19mm wheel and measure the movement of the twelve teeth along the wheel’s r
Four spindles on the trackball have a tiny circular magnet the end; each of these are paired with an SMD hall effect sensor, which are used to measure up, down, left and right movements of the trackball.
This ratiometric linear Hall-effect sensor provides a voltage output that is proportional to the applied magnetic field.
The Phidgets Linear Touch sensor feeds back your fingers position on the slider. Its and ideal touch interface to your PC!
When the WheelWatcher servo encoder is added to a standard-size RC servo, it accurately senses direction, distance, velocity and acceleration.
The Phidget Rotation Sensor is a 300 deg. Rotation sensor for the Phidget 8/8/8.
