The smart water controller for metro water supply lines described in this work makes use of a relay, an ultrasonic sensor, a flow sensor, a solenoid valve, GPS, and GSM. The planned system is intended ...

Application to Ultrasonic Sensors and Systems Abstract: This work presents in detail a new method for the optimization of rectangular spread spectrum excitation signals for its use in simple and ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...
