An Arduino radar system uses an ultrasonic sensor mounted on a servo motor to scan surroundings. The servo rotates from 0° to 180°, and the sensor measures distance at each angle. Data is sent to a PC ...

A simple radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and Servo Motor. The sensor rotates to detect objects by measuring distance. Results can be viewed via Serial Monitor.. - Pull ...

This paper proposes an automatic system that treats the household waste water to obtain optimum pH which is suitable for crop irrigation. Each plant species has a preferred pH and in general, the ...

Block compressed sensing (or sparse recovery) and its performance bound, i.e., conditions that guarantee reconstruction of the original sparse vector, have been widely studied. Most scenarios assume ...
