By soldering different resistors at a special location (or open, or shortcut), you can select the mode. To select four modes one would need two digital input ports, or one analog. To your question: Mine seems to have three “modes” – but there seem to be versions with up to five different “modes”.
ULTRASONIC SENSOR ARDUINO UNO PINOUT SERIAL
It seems that in the latest it is possible to put several of those boards on a bus and communicate via a serial interface. It seems also that there are different SW versions. I found several “manuals”, some better, some worse, some Chinese, some bad translations, none really good. If you have any questions, suggestions, or if you think that things are missing in this tutorial, please leave a comment down below. I would love to know what projects you plan on building (or have already built) with this sensor. If you did, please share it with a friend that also likes electronics! I hope you found it useful and informative. In this article, I have shown you how the JSN-SR04T ultrasonic distance sensor works and how you can use it with Arduino. Send ping, get distance in cm and print result (0 = outside set distance range): Measure distance and print to the Serial Monitor: 29ms should be the shortest delay between pings: Wait 50ms between pings (about 20 pings/sec). Open the Serial Monitor at 9600 baudrate to see ping results:

NewPing sonar = NewPing(trigPin, echoPin, MAX_DISTANCE) NewPing setup of pins and maximum distance. Maximum sensor distance is rated at 400-500 cm: Define maximum distance we want to ping for (in centimeters). *Arduino example sketch to control a JSN-SR04T ultrasonic distance sensor with NewPing libary and Arduino.
ULTRASONIC SENSOR ARDUINO UNO PINOUT CODE
I have included a modified example code below that can be used with the same wiring setup as before. The library does include some examples that you can use, but you will have to modify them to match your hardware setup.

The trigger pin is connected to digital pin 2 and the echo pin to digital pin 3 on the Arduino.

You should see the following output in the serial monitor: How the code worksįirst, the trigger pin and the echo pin are defined.

Print the distance on the Serial Monitor (Ctrl+Shift+M): pulseIn() returns the duration (length of the pulse) in microseconds: Trigger the sensor by setting the trigPin high for 10 microseconds: Begin Serial communication at a baudrate of 9600: * Arduino example sketch to control a JSN-SR04T ultrasonic distance sensor with Arduino. The Ultrasonic sensor can't do the echolocation stuff on its own though, so you will need to program it your self (don't worry, its not very difficult).įirst you should make sure you setup the pins correctly in your code (assuming you are using pin 13 as the Echo pin and pin 12 as the Trig pin).You can copy the code by clicking the button in the top right corner of the code field. The code will get the pulse inpu and output it onto the serial monitor. There is a demo code attached in the Code section. After the sound wave is sent out, the sensor will time how long it takes for the reflected sound to get back to the ultrasonic sensor. The operation is kind of like echolocation. There are many quick math equations you can use to convert the pulse time into a unit of measurement (note that these results may not be very accurate). The sensor outputs a muted sound wave out of its speaker (one of the silver barrels) that will bounce off an object and be reflected back to the sensor's microphone (the other silver barrel). In this tutorial I have the VCC connected to 5v, GND to GND, Trig to pin 12, and Echo to pin 13.
