Arduino ultrasonic sensor can send eight 40 kHz and detect whether there is any pulse signal back.If it back, a high level signal will be outputed by IO, and the duration of the signal is the time from sending ultrasonic to returning.
Specs:
- Working voltage 3.3V-5V
- Detection of reflection distance: 1mm ~ 25mm
- The comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA
- Output form: digital switch output (0 and 1)
- Using a wide voltage LM393 comparator
- With fixed bolt holes for easy installation
- With potentiometer adjustment sensitivity
- Using TCRT5000 infrared reflection sensor
