Hello: First of all I must start with the classic ""I`m new to this forum so excuse if this post is in the wrong section / this was already.... -
HI FRIENDS, I HAVE A ANIMAL REPELLER CIRCUIT CIRCUIT DIAGRAM AS SHOWN: I HAVE WRKED ON THIS BUT NOT WORKING AS PREFERRED CAN U PLEASE CHECK THIS ONE.... -
This is the electronic schematic of the homebuilt SONAR. Only one piezoelectric transducer is used for both transmit & receive. This transducer is switched from TX to RX via the four 4016 switches. A high gain amplifier stage & rectifier translates the.... -
There are many ultrasonic pest repellent devices available on the market but a major drawback is that their power output is low and their effectiveness suf.... -
This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit`s fine balance is disturbed and the alarm is triggered. The ultrasonic circuit.... -
This circuit generates inaudible ultrasound to make a barrier across the entry. At the moment the circuit detects a break in the sound barrier, it generates a loud alarm indicating the entry of a person. This can be used to protects the entry passages and.... -
This ultrasonic dog repeller circuit will chase away angry dogs. It is build with the all known 555 circuit, a buzzer and a little ferrite transformator. T.... -
LCD initializations in 8051 C programming words What is the logic behind the serial communication As in, how long should the SIG send out pulses and what should the delay be These statements are used to tell the compiler that a 16X2 LCD is connected to the.... -
The Panasonic transducers are no longer available, but the design is still interesting as an example. J1 is the connection to the RCX. D1 - D4 form a bridge rectifier to obtain local power from the RCX which is stored on C7 and regulated to 5V by U1, a low.... -
This is a vocational training report on Ultrasonic Proximity Detector undertaken under at Bharat Heavy Electrical Limited (BHEL)in partial fulfillment of the requirement for the Bachelor in Electrical engineering. The report covers topics like Making Printed.... -
This is a very interesting project with many practical applications in security and alarm systems for homes, shops and cars. It consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area.... -
As it has already been stated the circuit consists of an ultrasonic transmitter and a receiver both of which work at the same frequency. They use ultrasonic piezoelectric transducers as output and input devices respectively and their frequency of operation.... -
Hi guys this is my first tutorial, I`ve just started a few months ago learning electronics (previously I`ve just knew how to program in C and Python).... -
The circuit in Figure 1a and Figure 1b are the schematics of an ultrasonic proximity detector. It has a maximum detection range of approximately 6 ft. When someone passes in front of the ultrasonic transceiver board, the contacts of relay K1 will close. The.... -
Some ultrasonic range finders for my project. But most of the commercial sensors like Parallax`s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself The theory behind.... -
You could have an USBI2C with every sensor, which would mean 4-sensors for £120. The SRF02 runs on the I2C bus, which i`ve been told I shouldn`t extend more than ~2metres. The obvious plan would then be to have one USBI2C for the back bumper, and one for the.... -
By the ultrasonic sensor, control and display (or buzzer) and local composition, it can tell the driver his around obstacles by voice or a more intuitive display case. Relieve the driver stop, reverse and start to visit around the vehicle caused by problems,.... -
This section gives step-by-step instructions along with photos to the construction of Ultrasonic Proximity Receiver. Because this is a very simple circuit, only a schematic for the sensor is shown here: (For the PDF format click here. ) This tutorial`s.... -

The oscillation circuit of the transmitter was added. An oscillation circuit by 555 IC is used for a modified circuit. This is to adjust an oscillation frequency easily. Thereby, it is necessary to change the software... -
The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. Generally, the.... -
The alarm detector circuit is different from Ultrasonic Alarm (1). In Ultrasonic Alarm (1), an alarm output is presented when there is a reflected wave from the object in the setup time. At the circuit this time, an alarm is output when no reflected wave.... -
An ultrasonic beacon and a ultrasonic receiver is very similar to a beam barrier circuit, the only difference is we don`t sound an alarm when an object breaks the ultrasonic path, but instead we try to locate the ultrasonic beacon by moving the receiver..... -
The circuit described generates (transmits) ultrasonic sound of frequency between 40 and 50 kHz. As with any other remote control system this cirucit comprises of a mini transmitter and a receiver circuit. Transmitter generates ultrasonic sound and the....

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.....
