An Arduino-based automatic water tap using an ultrasonic sensor and a micro servo is an innovative and convenient project.
The ultrasonic sensor is used to detect the presence or absence of an object, such as a hand, beneath the tap. When the sensor detects an object within a certain range, it sends a signal to the Arduino microcontroller.
The Arduino then processes this signal and controls the micro servo to open or close the water tap accordingly. The micro servo acts as the actuator that physically moves the tap handle or valve to control the water flow.
This setup offers several benefits. It helps conserve water by only dispensing water when needed, reducing wastage. It also provides a hands-free operation, which is hygienic, especially in public places.
For example, in a public restroom, this automatic water tap can be installed to minimize the spread of germs. Or, in a home kitchen, it can make the water usage more convenient while ensuring efficient water consumption.
To build such a system, one needs to have a good understanding of Arduino programming, electronics circuitry, and the proper calibration of the ultrasonic sensor and micro servo for accurate and reliable operation.
