How to Make Ultrasonic Remote Control Circuit | Homemade ... The proposed ultrasonic remote control circuit uses ultrasonic transducers to produce and receive the ultrasonic signals. Ultrasonic transducers are used in measuring the distance of an object and various other applications. In this circuit, we use them for a different purpose of making a remote controlled relay. How to Make a Ultrasonic Remote Control Circuit The recommended ultrasonic remote control circuit utilizes ultrasonic transducers to deliver and acquire the ultrasonic signals. Ultrasonic transducers are being used in measuring the distance of an object and several other programs. In this circuit, we give them a try for another objective of generating a remote controlled relay. 4QD TEC: Ultrasonics: remote control and Intruder detector Ultrasonics: remote control and Intruder detector This transmitter is designed to work with the next circuit as a remote control transmitter receiver. It is only a single channel and you could once get multi channel chips for the whole job. Become Device Maker: ULTRASONIC REMOTE CONTROL ULTRASONIC REMOTE CONTROL H ere is a low cost, wireless switch controller. It uses ultrasonic sound waves for remote control of a switch. As with any other remote control, the system basically comprises a transmitter and a receiver circuit. AES E Library » Ultrasonic Capsule for Remote Control Purposes Ultrasonic Capsule for Remote Control Purposes Description of a highly sensitive ultrasonic capsule which may be used both as an acoustic transmitter and receiver. The acoustic properties of this transducer will be shown by electromechanical equivalent circuit and its mechanical construction will be described in detail. Ultrasonic switch Electronic Circuits and Diagrams ... Description. A different type of remote control circuit employing ultrasonic signals is given here. The transmitter part of the circuit is build around IC1(NE 555).The IC1 is wired as an astable multi vibrator operating at 40KHz.The output of IC1 is amplifier the complementary pair of transistors ( Q1 & Q2) and transmitted by the ultrasonic transmitter K1.The push button switch S1 is used the ... Ultrasonic transmitter receiver circuits Free ... Since the circuit only for one way signal amplifier, when an ultrasonic signal transmitters each transmitter, the receiver relay time (time to pull the same time with the transmitter transmitting the signal), with no memory retention function. Used as a wireless remote camera shutter control, control of children’s toys, curtains and control. Ultrasonic Transmitter and Reciever | Circuit Diagram ... Ultrasonic receiver circuit The receiver circuit (Fig.2) is built around a single decade counter CD4017 (IC4) and a few discrete components. To check the working of the transmitter, it is necessary to down convert the 40kHz signal into 4kHz to bring it in the audible range. How to Set Up an IR Remote and Receiver on an Arduino ... Each time you press a button on the remote control, a unique hexadecimal code is generated. This is the information that is modulated and sent over IR to the receiver. In order to decipher which key is pressed, the receiving microcontroller needs to know which code corresponds to each key on the remote. ultrasonic transmitter circuit Arduino Forum I'm pretty sure the ultrasonic transmitter was broken when the remote was dropped. It will work if I hold it less than an inch from the receiver, but otherwise doesn't work. I am considering replacing the ultrasonic reciever and motor driver circuit with an arduino or Spark Core (Particle Photon). ULTRASONIC REMOTE CONTROL (Wireless Switch) It uses ultrasonic sound waves for remote control of a switch. As with any other remote control, the system basically comprises a transmitter and a receiver circuit. Frequencies up to 20kHz are audible. Frequencies above 20kHz are not audible. The transmitter circuit generates an ultrasonic frequency between 40 50kHz. The receiver senses the ultrasonic sound and switches on a relay. Ultrasonic Transmitter questions | Electronics Forums ultrasonic remote control with TX and RX circuits capable of sending and receiving serial data. I've been at it off and on and so far I have it working as far as the TX circuit sending a single byte with a US Patent for Ultrasonic remote control receiver suitable ... Ultrasonic remote control receiver wherein reference frequency pulses are counted during a counting cycle comprising a predetermined number of received command signals, each command signal occupying a different frequency channel. At the end of each counting cycle, the reference frequency count is compared with the count during the preceding counting cycle. High power remote control ultrasonic transmitter RCA ... High power remote control ultrasonic transmitter ... This invention relates to ultrasonic remote control transmitters and more particularly to an ultrasonic transducer drive circuit having broad bandwidth and low power dissipation. ... for example, a respective plurality of ultrasonic frequencies for which the remote control receiver is ... Ultrasound Generator Ultrasonic Circuits Electronics ... As with any other remote control system this circuit comprises of a mini transmitter and a receiver circuit. Transmitter generates ultrasonic sound and the receiver senses ultrasonic sound from the transmitter and switches on a relay. Ultrasonic Alarm This alarm device transmits the ultrasonic and it confirms a reflected wave from the obstacle.
