Introduction: Sonic Wave Recorder

Picture of Sonic Wave Recorder

First, I am a novice to the field of electronics and micro-controllers, started just 3 weeks ago, with an aspiration to make some devices for my field data collection. Here is what I created - an ultrasonic wave recorder. I shall mount the SONAR [ping))] sensor from a fixed platform having it pinging downward on the water surface and measure instantaneous change in distance (at about 8-10Hz) and write the data on a microSD card. Here is an early picture of what I have wired on a breadboard. After this picture I have included 3 LEDs to indicate Error (Stay Red), SD OK (Stay Green) and 'data logging in progress' (Blinking Amber). I have also included an LM35 digital temperature sensor and record its data, so that I can apply more accurate calculations of the speed of sound at the time of data acquisition. Hence I am recording one-way travel time in microseconds as well. Now I am working on a switch which will Start/Stop data logging. And then I will work on the battery issue. The second picture is a snapshot of the data captured by the device.

I hope to write a full step-by-step instructable once I am done, all credits with link, and the complete Arduino sketch will accompany at that time. I am so excited that I cannot help not sharing a picture now :p Pardon my excitement!

very cool. I look forward to elearning from your experience I am looking to build a device which I hope to use this tech over using a webcam and image detection. And resources you can share on the subject would be greatly appreciated.

BTW, you could add this to the Data Visualization contest

Is it done?

... and here is a photograph of the finished thing!

Sorry about the long silence since I posted this photo. Yes, it is done to the extent I wanted it to be, and is currently undergoing some serious testing and field trials. I shall be back as soon as I get some presentable data. Thanks for your interest.
