Description:

This is ultrasonic sensor distance measuring module which a non-contact distance measurement module. It has high measurement accuracy and its blind area is close (up to 2cm).

Features:

• Using IO trigger for at least 10us high level signal
• The module automatically sends eight 40 kHz and detect whether there is a pulse signal back
• If the signal back, through high level ,time of high output IO duration is the time from sending ultrasonic to returning.
• Test distance = (high level time velocity of sound (340M/S) /2
• Power supply: 5V DC, quiescent current: <2mA, effectualangle: <15, ranging distance: 2cm~500 cm, resolution: 0.3 cm

Documentation and Support:
