SHAPED TRANSMITTER CONE FOR PING TYPE ULTRASONIC SENSOR
A low cost way to wring the maximum DIRECTIONAL performance from your ultrasonic range finder...and it looks cool too!
Improves the following performance characteristics:
The directional properties of the unit (senses in the direction pointed)
The sensitivity of the unit
Smaller targets can be detected
Better luck detecting acoustically "soft" targets like cloth, stuffed animals, fur etc.
When used with larger receiver cone range is dramtically improved
How to use:
Simply slip the unit over the case of the transducer for instant improvements over no cone at all
For a more permanent assembly a piece of tape to increase the friction fit or a dab of glue
Use one on the receiving transducer for modest gain
Use one on the transmitter and one on the receiver for maximum gain
Mix and match with other shaped cones to tailor the gain and directional properties to match your application
*Warning! The range can be increased to the point that detection of "old" ping signals results in erratic readings if range to target and speed of sound is not taken into account.
