Water Level Sensor Arduino Circuit Diagram

The circuit diagram is quite simple with only a few components but it can perform a great number of tasks as a monitor for the desired level of any fluid.

Water level sensor arduino circuit diagram.

In this project two circuits are used. One output gpio pin is directly connected to the water level sensor and sends a 3 3 v signal to the sensor with a duration of just 200 milliseconds. As shown in the water level controller circuit given below ultrasonic sensor module s trigger and echo pins are directly connected to pin 10 and 11 of arduino a 16x2 lcd is connected with arduino in 4 bit mode control pin rs rw and en are directly connected to arduino pin 7 gnd and 6. Arduino water level indicator circuit.

Transmitter circuit transmitter circuit is shown in the figure below fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino. Hi sir good afternoon i am trying to interface the water level sensor using arduino nano for harvesting the fish aquarium automatic water level detecting and filling the water below average of water but the tank depth was 45cm the sensor size only the 5 cm how to apply the same application using long height sensor or if any chance to increase the size of sensor please reply this question sir. In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. Circuit diagram and explanation.
