Circuits Designed by Dave Johnson, P.E. :

  • 40Khz Ultrasound Receiver -  A X100 transistor Amplifier is followed by a zero cross detector circuit, using a voltage comparator. The output is a TTL logic signal, corresponding to the received 40KHz signal . . . [Circuit by David A. Johnson P.E.,  01/29/06] 

  • 40Khz Ultrasound Transducer Driver uses Medium Power -  This crystal controlled circuit drives a 40KHz piezo transducer with a 30v peak to peak signal . . . [Hobby Circuit designed by David Johnson P.E.,  01/29/06]

  • Medium Power 40Khz Ultrasound Transducer Driver -  This crystal controlled circuit drives a 40KHz piezo transducer with a 30v peak to peak signal . . . [Circuit by Dave Johnson P.E.,  01/29/06]

Cheap Ultrasonic Range Finder based on PIC16F877A with a 8MHz crystal -  Everybody knows the speed of the sound in the dry air is around 340 m/s. Send a short ultrasonic pulse at 40 Khz in the air, and try to listen to the echo. Of course you won't hear anything, but with an ultrasonic sensor the back pulse can be detected. If you know the time of the forth & back travel of the ultrasonic wave, you know the distance, divide the distance by two and you know the range from the ultrasonic sensor to the first obstacle in front of it. . . .  [by Bruno Gavand]
