Water Level Sensor Arduino Circuit Diagram

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.

Water level sensor arduino circuit diagram.

Arduino water level indicator circuit. In this tutorial we are going to make a simple water level sensor or liquid level detector circuit. 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. The esp 32 is powered with 5 v from the usb port and has a 3 3v regulator on board.

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. This circuit measures or detects a required level of water liquid or any fluid. 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. Circuit diagram of arduino water level indicator and control using ultrasonic sensor hc sr04r below is the code of the design with the explanation of the codes written inside the as comments.
