Pololu Distance Sensor w/ Pulse Width Output 50cm TFT Display wie laufende MotorenThis small lidar based distance sensor reports the distance of objects up to about 50 cm away with a pulsed signal similar to a hobby servo control signal. A digital microcontroller pin can be used to time the length of each high pulse, which encodes the measured distance. The sensor works over an input voltage range of 3. 0 V to 5. 5 V, and the 2. 54mm pin spacing makes it easy to use with standard solderless breadboards and 2. 54mm perfboards. Note:
