Description

The Grove ultrasonic ranger offers a really simple way to connect into an Arduino-compatible environment (especially when using a Seeed Grove base shield). There may be more “intelligent” and enhanced ultrasonic rangers on the market, but this unit is a bargain in performance, cost, and ease-of-implementation.
