Ultrasonic Sensor Raspberry Pi Circuit

Below is the circuit diagram for connecting hc sr04 sensor and lcd with raspberry pi for measuring the distance.

Ultrasonic sensor raspberry pi circuit.

There are four pins available in ultrasonic distance sensor. Left sided pin vcc is connected to 5v trigger pin is connected to gpio 4 echo pin connected to gpio 17 and gnd pin is connected to raspberry pi ground pin. A basic ultrasonic sensor consists of one or more ultrasonic transmitters basically speakers a receiver and a control circuit. The raspberry pi ultrasonic sensor interface is different from interfacing led button lcd motors etc.

I have been asked to prepare a code that works on python to control 8 ultrasonic sensors connected to a raspberry pi board. Make the circuit as per the given diagram. These small modules are available starting at 1 2 bucks and can measure the distance up to 4 5 meters by ultrasound and are suprisingly accurate. The sensor i choose for such a project is the hc sr04 sensor.

Ultrasonic distance measurement with raspberry pi raspberry pi piday raspberrypi here s an excellent project for to make ultrasonic distance measurements. We power the module using vcc ground it using gnd and use our raspberry pi to send an input signal to trig which triggers the sensor to send an ultrasonic pulse. From radu mihai rotariu via hackster io. Below are all the bits and pieces that we utilized for this guide on setting up a raspberry pi distance sensor circuit.

This tutorial shows the connection and control. The hc sr04 ultrasonic sensor we ll be using in this tutorial for the raspberry pi has four pins. As shown in the figure hc sr04 ultrasonic sensor has four pins pin1 vcc or 5v pin2 trigger 10us high pulse given to tell the sensor to sense the distance. Connect one end of the 330ω resistor to the echo pin.

Control a ultrasonic distance sensor with scratch for raspberry pi and use in the ultrasonic theremin project of magpi magazine issue 58 note the project uses a python program to send the sensor data to the scratch program. Ultrasonic theremin with scratch for raspberry pi. Raspberry pi 2 or 3. The system shall be connected to a screen via an hdmi and it should show something like a radar monitor.

A brief note on ultrasonic sensors. Using a raspberry pi distance sensor ultrasonic sensor hc sr04 for many outdoor projects a distance measurement is necessary or advantageous.
