Arduino – Water Detector
What are the three terminals of the water sensor?
The water sensor has three terminals namely power pin, signal pin and ground(GND).
What is the difference between digital and analog water sensors?
The digital water sensor is used to tell whether water is present or not whereas the analog water sensor is used to tell the level of water by generating a proportional voltage level.
Which PIN is used for taking input and giving output?
The input is taken at pin number 8 of Arduino and output is generated at pin number 9.
Arduino – Water Detector / Sensor
Sensors are widely used for detecting different quantities like the presence of light, level of water, etc. One such example of a sensor is the water sensor which uses various principles of physics to detect the presence of water. This sensor is known for detecting different water levels with accuracy and precision.
This article will talk about the design of a water sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor. In order to understand the functioning of the sensor, we will study the principles of the sensor. In addition to this, we will see the Arduino code written on IDE that will result in a sensor. The article will end with some frequently asked questions that can be referred to by readers.
