KSR504 REFLECTIVE ULTRASONIC DETECTOR

$4.98

Description

The KSR504   REFLECTIVE ULTRASONIC DETECTOR Module offers non-contact detection of objects (or people) in the range 2cm to 400cm. It can also be used as a distance measuring device with an accuracy down to 3mm over its practical range. The module consists of an ultrasonic (40KHz) transmitter and a matching receiver with the necessary control circuitry.

The unit works, upon a command of 10uSec or more,  by sending a series of 8 pulses and “listening’ for any reflected pulse.  A detected signal may be treated as a simple “object in range” signal or can be compared with the timing of the transmitted signal to determine the distance to the detected object through the formula: Test Distance= High Level time x velocity of sound (340metres/second)/2.

The following connections are available to the user:  1. +5V Supply 2. Trigger Pulse Input 3. Echo Pulse Output and 4. Ground.
