Ultrasonic
Ranger SRF04
 |
This high performance ultrasonic range
finder is compact and measures an amazingly wide range from 3cm to 3m.
This ranger is perfect for your robot, or any other projects requiring
accurate ranging information. The SRF04 is a straight-forward ultrasonic range sensor. The host microcontroller provides a positive going pulse on the INIT pin on the sonar module to begin a reading. After the INIT input pin goes low, the sonar module emits a ping. After the ping, the ECHO output goes high. It returns low again when the module receives an echo. More information can be found here. Software examples for different microcontrollers can be found here.
