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 ...

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 ...

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 ...

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.

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 ...

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 ...
