The ultrasonic sensor measures the distance from the sensor to the water surface, which is then used to calculate the water level as a percentage. Based on this value, the Arduino decides whether to ...

Project description In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to ...

As shown in the block diagram, the Arduino microcontroller constantly monitors the values from the ultrasonic sensor which is placed outside the dustbin. When a person comes near the dustbin the ...

How the Arduino ultrasonic sensor actually works To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...
