Ultrasonic distance sensor

May 8th, 2009

The ultrasonic distance sensor, sends out an ultrasonic pulse and measures how long it takes for a reflection to get back to the device. The longer this takes, the further away the sensor is from an object.

From the robotshop website:

SRF05 - Ultrasonic Range Finder.

Voltage - 5v only required
Low Current - 4mA Typ.
Frequency - 40KHz
Max Range - 4m
Min Range - 1 cm
Modes - Single pin for trig/echo or 2 Pin SRF04 compatible.
Input Trigger - 10uS Min. TTL level pulse
Echo Pulse - Positive TTL level signal, width proportional to range.
Small Size - 43mm x 20mm x 17mm height

Amount in workshop: 2
