    Hi all, I have to make a simple circuit with an EESPY401/402

    I thought to put a buzzer connected to the output pin, connecting the buzzer to the Vcc and the output voltage to make it turn on when the sensor detect some object.

    But in the datasheet example, it figure a relay as Load 1. If I don't use a relay, my idea would be ok?

    Thank you.

    Hello,

    It also depends on the type if buzzer you want to use.
    If you want to use some piezo beeper, take care it has a buildin oscillator.

    So, If I would like to put a relay, just connect the coil to Vcc and Out (as I thought for the buzzer), and connect the buzzer to the NO of relay and ground. This should be also Ok if I am not making errors. Right?

    Hi Bertus, thank you, but I forgot to say that the circuit will just be theoric, anything practice. I don't think this will be really important, but I keep in mind your suggestion, I did not know this detail.

    Thank you
