Hi all,
Please tell me what hardware and software we need to buit the ultrasonic translator to capture the wave form from another sensor?
Tahk you for your time.

I'm using the ultrasonic distance transducer to detect object, but it does not work properly in a room that have DT-205 (dual technology motion sensor·- combine PIR and·ultrasonic 40KHz·in one unit). So, I want to build a ultrasonic translator on the ultrasonic distance sensor, it can capture the ultrasonic sound from the DT-205. It is possible or not? do you have any advise?
Thank you for your time.
To get these two devices to work in the same space, you need for them to work on widely different frequencies and you can't modify either device (not realistically). A frequency translator, while theoretically possible, isn't practical and would be way more complicated than simply duplicating the function of the PING at a different frequency.
The PING works by measuring the time it takes for the sound pulse to return to it. For it to use the pulses from the DT-205, it would have to know exactly when the DT-205 produces its pulse and the PING would have to "know" where the DT-205 is in the room so it could compensate for the distance and direction of the sound source.
The simplest solution would be to switch to the use of IR for object detection like that described (and used) in "Robotics with the BoeBot".

"puff"...... Smile, there went another one.
Can you tell me more how to duplicate function of ping))) sensor with different frequentcy.
Thank you for your time.
