RAM Electronics's Description
Distance measurement sensor is a low cost full functionality solution for
distance measurement applications. The module is based on the measurement of
time flight of ultrasonic pulse, which is reflected by an object. The distance
to be measured mainly depends on the speed of ultrasonic waves in space or air
–which is a constant- and the flight time of the pulse.
The module performs these calculations and outputs a pulse width depends on
the measured distance, this pulse is easily interfaced to any microcontroller.
