This compact sonar range finder by Maxbotix detects objects from 0 to 6.45 m (21.2 ft) with a resolution of 2.5 cm (1") for distances beyond 15 cm (6"). Unlike other sonar range finders, the LV-MaxSonar has virtually no dead zone: it can detect even small objects up to and touching the front sensor face!

The EZ0, EZ1, EZ2, EZ3, and EZ4 versions have progressively narrower beam angles.

Price: $44.95
Quantity:

This ultrasonic (sonar) range finder features real-time automatic calibration and noise rejection resulting in virtually noise-free distance readings even in environments with changing acoustic and electrical noise. The sensor detects objects from 0 to 7.65 m (25 ft) and has a resolution of 1 cm (0.4") for distances beyond 20 cm (8"). The XL-MaxSonar works from 3.3 to 5V and peaks at only 0.5 W of power consumption.

The EZ0 / AE0, EZ1 / AE1, EZ2 / AE2, EZ3 / AE3, and EZ4 / AE4 versions have progressively narrower beam angles.

This easy-to-use distance sensor from Parallax employs sonar to detect objects from approximately 0.75 – 120 inches (2 cm – 3 meters). The Ping distance sensor has status LEDs and requires only one I/O pin. The on-board three-pin header makes the PING))) compatible with a solderless breadboard.
