Ultrasonic Transmitter With IC 555
Ultrasonic transmitter With IC 555 is a simple circuit that can transmit ultrasonic waves. Ultrasonic wave transmitter in the article “Ultrasonic Transmitter By IC 555” prepared by an ultrasonic transducer that given the input square wave with a frequency around 40 KHz is generated by the astable multivibrator with IC 555. Square wave generated by a multivibrator circuit composed by IC 555 that work in astable then given to the module or “tranduscer ultrasonic” for the send out. Ultrasonic transmitter circuit shown the following figure.
