Working of the Water Detector
Let us see the working of a water sensor based on Arduino
Working of Water Detector Sensor
- The sensor is made up of some copper traces. The count of these traces is 10, 5 of which are for power and the other 5 for sensing purposes. The parallel connection of traces allows the presence of one sense ambushed between two power traces.
- The traces can be understood as variable resistors similar to potentiometers that change the circuit resistance depending on the water level.
- The resistance varies inversely with the height of the water level. Therefore, when the maximum water level is present, the resistance is minimum and conduction is maximum.
- When the minimum water level is present, the resistance is maximum and conduction is minimum Therefore, the output voltage produced by the sensor will vary directly with the water level.
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.
