This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

If you have played with ultrasonic distance measurement projects, I’m sure you have at some point played with the HC-SR04 Ultrasonic ... Below is the Arduino Sketch used to test the JSN-SR04T ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

He wanted to use the less expensive HC-SR04 ultrasonic ... the Arduino library to accept the two pin approach. But with his long term goal in mind, he also modified the HC-SR04 sensor by removing ...
