Ultrasonic sensor circuit is a sensor that consists of transmitter and receiver. This circuit is useful for remote control. The frequency of sound produced by a series of Ultrasonic Sensor is above 20 KHz which is between 40 KHz 50 KHz. Used power supply voltage is 9 V battery cans so use with a voltage of 9 V. How it works is a series of ultr

asonic sensors in the circuit if the switch is pressed then the transmitter will from send signals received by the receiver circuit. Ultrasound acoustic wave having a frequency of 20 kHz to about 20 MHz. The Following is a schematic drawing: where s is the distance in units of meters, v is the speed of sound is 344 m / s and t is the travel time in seconds. While most obstacles ultrasound waves are reflected partly absorbed and some other people will be continued. Ultrasonic sensor is a sensor that changes the physical quantities (sound) to the amount of electricity. In this case an ultrasonic wave sensor generated through an agency called piezoelectric. This will produce piezoelectric ultrasonic waves with a frequency of 40 kHz when an oscillator is applied to the object. Ultrasonic sensors typically used for a disclosure does not touch such a variety of measurement applications. This tool is generally emit ultrasonic sound waves toward the target that reflects the waves back toward the sensor. The system measures the time required for the transmission of waves to go back and calculate the distance to the target sensor by using the speed of sound in the medium. Compiler series ultrasonic sensor consists of transmitter, receiver, and comparator. In addition, ultrasonic waves generated by a thin piezoelectric crystals. Direct piezoelectric equipment change electrical energy into mechanical energy. Input voltage causes a...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
