Using an ultrasonic sensor to measure distance Overview. For sensors like the VEX Ultrasonic sensor that return a range of values, we often simply want to check if the returned value is more than, equal to, or less than some value called a threshold. For example say that we have the sensor set up and are driving around, but we need to stay at least 5 inches (127 mm) away from any obstacles.

- Quick Answer. Ultrasonic sensors work by transmitting energy in the form of ultrasonic waves to a target object, which reflects the waves back to the sensing head. Ultrasonic sensors are largely used in measuring distances based on the time it takes for the wave transmission and reception to be completed. Continue Reading.

Ultrasonic cleaning Ultrasonic cleaner showing the removable basket in place, and a closeup of the light and timer. An ultrasonic cleaning is a process that uses ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean items.The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned along with the soiling enhances the effect.ltrasonic cleaners are used to clean many different types of objects, including jewellery, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, fishing reels, window blinds, firearms, musical instruments, industrial parts and electronic equipment.

Ultrasound Ultrasonic sensors “are based on the measurement of the properties of acoustic waves with frequencies above the human audible range,” often at roughly 40 kHz . They typically operate by generating a high-frequency pulse of sound, and then receiving and evaluating the properties of the echo pulse. Three different properties of the received echo pulse may be evaluated, for different sensing purposes.

Doppler ultrasonography All modern ultrasound scanners use pulsed Doppler to measure velocity. Pulsed wave machines transmit and receive series of pulses. The frequency shift of each pulse is ignored, however the relative phase changes of the pulses are used to obtain the frequency shift (since frequency is the rate of change of phase).

- For this reason most delicate parts are cleaned in a high frequency ultrasonic tank. [ 70 to 200 kHz. By distributing the total energy of the tank over a greater number of energy peaks the overall effect is to create a very homogeneous power distribution and subject the part to an even level of energy.

Ultrasonic Pest Repellers: Solution or Scam? In summary, ultrasonic pest repellers emit high-frequency sounds that manufacturers claim reduce household pest infestation, but laboratory tests have shown that the majority of such devices do not work as advertised, in violation of FTC guidelines.tudies designed to investigate the efficacy of ultrasonic pest repellents have shown mixed results. One extensive test performed by Kansas State University in 2002 found that the devices were effective at repelling some insects, such as crickets, but the same devices had little effect on cockroaches.

Ultrasound Ultrasonic sensors are based on measuring the properties of sound waves with frequency above the human audible range. They are based on three physical principles: time of flight, the Doppler effect, and the attenuation of sound waves. Ultrasonic sensors are non-intrusive in that they do not require physical contact with their target, and can detect certain clear or shiny targets otherwise obscured to some vision-based sensors. On the other hand, their measurements are very sensitive to temperature and to the angle of the target.
