The HC-SR04 Ultrasonic Distance Sensor is a sensor used for detecting the distance to an object using sonar. It's ideal for any robotics projects your have which require you to avoid objects, by ...

Arduino Ultrasonic Sensor Code for Distance Measurement The complete code for this ultrasonic distance measurement project is given at the bottom of this page. In the code we read time by using ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

Hardware system consist of basically 3 components named as Arduino, servo-motor, and ultra-sonic sensor. Ultrasonic sensor is mounded upon a servo motor which helps it to move and provide it a turning ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

The JSN-SR04T Waterproof Ultrasonic Sensor As well as the familiar ultrasonic ranging module HC-SR04, another one seen on online markets is the JSN-SR04 (and variants). The JSN-SR04 ultrasonic ranging ...

[lingib]’s dual sensor echo locator uses two HY-SRF05s, but the cheap and plentiful HC-SR04s will work, too. Both sensors are arranged for maximum beam overlap and wired up to an Arduino Uno.
