This quick dirty PIC ultrasonic range finder will find a place in numerous projects: presence detector, robotics, car parking, distance. 01/21/99 EDN-Design Ideas - (Scroll to find this one) As digital communications and data compression/decompression proliferate, signal-processing functions grow in importance. Whether you’re dealing with hard-wired logic or programmable engines, an understanding of binary-arithmetic rounding is important in getting correct and consistent results.

Before we discuss rounding, consider a binary number (Figure 1) Page includes several designs. __ Circuit Design by Tom Balph, Motorola SPS, Tempe, AZ 04/21/11 EDN Technical Article: Use an ultrasonic transducer to measure air temperature in an olive jar.

__ Circuit Design by Jim Williams, EDN's most revered contributor, passed away in June 2011 after a stroke. Build it and avoid those parking mishaps. __ SiliconChip Linear Technology AN131 __ Designed by Jim WilliamsApr 26th, 2011 The Simple Bat Detector is a frequency division type device. Frequency division type detectors allow you to hear ultrasonic sound by digitally scaling the frequency down into the human hearing range.

For instance, a western pipistrelle bat emits ultrasonic sound in the range __ Designed by Tony Messina-Las Vegas, NV Most readers would know that you can obtain small ultrasonic cleaners for jewellery and similar small items. So why not a much larger version? It would be great for cleaning automotive and other mechanical parts, fabrics which cannot be machine washed, ornate bric-a-brac and a host of other hard-to-clean items. __ SiliconChip The Simple Bat Detector is a frequency division type device. Frequency division type detectors allow you to hear ultrasonic sound by digitally scaling the frequency down into the human hearing range. For instance, a western pipistrelle bat emits ultrasonic sound in the range __ Designed by Tony Messina-Las Vegas, NV Detect objects through ultrasonic sound waves. Vcds clone interface not found.

__ Contact: Jameco Electronics - Circuit Ideas for Designers App Note __ Advanced Linear Devices, Inc - Circuit Ideas for Designers App Note __ Advanced Linear Devices, Inc - 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.
