ultrasonic sensor

As part of my ongoing project, I need to drive a Piezoelectric ultrasonic speaker. I have 1 of each that resonates at 20khz and 25khz. The max my sine wave oscillator can give out is 5v RMS, and the max the speakers can handle is 20v RMS. So to get the max out of the speaker I need a...

Hi, I am working on a project to measure distance between two objects (A and B) using Arduino. Both these two objects are moving with time among other objects, but there is always a Line of sight available (assumed for now). After some research I concluded to use ultrasonic sensors. My idea is...

This is a system to detect any intruders using ultrasonic sensor . The buzzer should ring if the timer gets triggered . Somebody help me with the simulation using proteus or any other softwares

Hello Here I am again with the car, but now there is no problem with control :). I just added an ultrasonic sensor to the front of the car, with the fact that if the distance is less than 20 cm, it should stop. When the car is running, it works once or twice, but on the third attempt, the car...

Hi, I'm developing an ultrasonic sensor to measure the depth of the sludge in large tanks. But for now i'm trying to measure water depth. My transducer is the TD40200D, it's recommended 1000vpp supply but it should works fine with 300vpp for my needs. I have no ideia how to start it, does anyone...
