It has a plastic valve body with a rotor and a hall sensor circuit.
Water sensor diagram.
As clearly indicated in the circuit diagram two closely spaced metal rings are used as the water sensor mechanism.
It can be used to detect the presence the level the volume and or the absence of water.
Water switch circuit schematic.
S this output goes to any analog signal on arduino.
The value of conductance current depends on the ratio or level of water.
Anyone can do it.
Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc.
It has three wires namely 5v red gnd black and output yellow.
Incoming analog signal read and appointed sensor serial println sensor.
This project is very basic.
In the below diagram water sensor circuit and how it works is broadly highlighted.
The water level indicator circuit diagram monitors the level of water in the tank and simultaneously switches on the water pump whenever the water level goes low in the water tank.
When arduino water level sensor is continuously exposed to.
Communication started with 9600 baud void loop int sensor analogread a1.
Water flow sensor as the name suggests is a device to measure the flow of water.
However one can use two metal needles injection needles to make the sensor.
The water flow sensor used in this project is shown in the image below.
Wrote serial port let s prepare the circuit.
Flow sensor photoelectric sensor.
The water level of the tank is indicated by using the 5 led s and if the water level in the tanker is full then the water pump is turned off completely.
