    300 Khz ultrasonic transreciever

    Hello,
    my name is love. can anyone please guide me with circuit diagram with which i can drive a Ultrasonic transducer.
    there are various circuits available for driving 40KHz transducer via arduino but none for 300KHz.
    i just need to drive the transducer and generate US pulse via arduino

    Thankyou

    Hi,

    Missing informations: voltage, current, power, waveform...

    Suitable circuit depends in the above informations.

    Not sure what the problem is. Behavior of 300 kHz transducers is similar to 40 kHz types, with respectively scaled frequency.

    Re: 300 Khz ultrasonic transreciever



    how to drive this using Arduino it just has 2 pins and where to connect it to Arduino.I just want to generate a pulse which is transmitted and received by reflecting from a surface.Please help me.
    Or what can I use to drive this transceiver?
    Please help me

    Re: 300 Khz ultrasonic transreciever

    Sir,
    I am making a project, in which I have to send a wave via transceiver and that wave get reflected by a surface and received by receiver ,these are the parameter which I have to achieve for proper resolution (frequency of 300kHz and the bandwidth of 20kHz, the pulse repetition interval (PRI) is 600us and pulse number, M is 12).
    Basically, I am trying to sense hand movements.
    Please help me, tell me if you need any other info

    Just like this, this is the structure of HC-SR04, I need the same for 300 KHz transceiver.
    please help me.

    Re: 300 Khz ultrasonic transreciever

    HC-SR04 contains a burst generator and receiver amplifier, the same function need to be implemented for the 300 kHz transducer.

    Re: 300 Khz ultrasonic transreciever

    Can you please explain to me how to connect and what should be the parameters for achieving that pulse?

    Re: 300 Khz ultrasonic transreciever

    Lovegupta, I don't think you are understanding why the questions are being asked.

    Transducers come with many different specifications and we have no idea what they are for the one you show. Some have built-in electronics, some do not. They also have different ratings and drive requirements so giving the wrong advice either may not work or could damage the transducer.

    Producing 300KHz should be fairly easy although I'm not familiar with Arduino capabilities but how it connects to the transducer could be complicated. Some 40KHz transducers need >100V to fully drive them for example, so just connecting it to the Arduino pins is unlikely to work.

    Brian.
    PLEASE - no friends requests or private emails, I simply don't have time to reply to them all.
    It's better to share your questions and answers on Edaboard so we can all benefit from each others experiences.

    Re: 300 Khz ultrasonic transreciever

    how can I generate an ultrasonic pulse from this 300 KHz transceiver.please help me anyway just to start this and send a pulse?make your own assumptions, just tell me how it will start and can generate a pulse
