The JSN-SR04T Waterproof Ultrasonic Sensor. ... Below is the Arduino Sketch used to test the JSN-SR04T ultrasonic distance sensor. This sample code does not require a library. ... Basically, I just ...

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 ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

How They Work. The design of a robotic ultrasonic system is similar to collision avoidance and parking systems in cars. For example, ultrasonic sensors are embedded on the sides of a robotic vacuum to ...
