If water enters the electronic module ... Stay tuned for that do it yourself project. Below is the Arduino Sketch used to test the JSN-SR04T ultrasonic distance sensor. This sample code does not ...

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 ...

I've thought about building an ultrasonic water level sensor ... I got my float sensors in today and have it connected to an arduino uno. Easy enough to read the value and seems to work just ...

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 ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...
