Sonar Phidget<\/h1>\n

The Sonar Phidget measures distance using ultrasonic pulses. It sends out a pulse and waits for a reflection to come back. Distance is calculated by timing how long the pulse took and knowing the speed of sound.\u200bThe Sonar Phidget returns distance measured in millimeters (symbol: mm). You can easily convert this measurement into a unit you are familiar with, like meters or feet.<\/pee> <\/p>\n
