How to wire water level sensor Arduino?
Connect the VCC of the sensor to the Digital pin 7 of the Arduino. Connect GND of the sensor to the Ground of the Arduino. Connect the cathode of RED, YELLOW, GREEN LED to the 2,3,4 digital pin of the Arduino respectively. Connect all anodes of the LED commonly to the GND pin of the Arduino.
How do you measure water depth with a sensor?
With ultrasonic sensors, we can find the water depth calculation by finding the distance between the transceiver and the surface of the water. The sensor will transmit a short ultrasonic pulse, and we can measure the travel time of that pulse (the echo) to the liquid and back.
Can HC SR04 detect water?
The sensor shoots a short ultrasonic pulse at the surface of the water, then based on the time of its echo to return, as well as the speed of sound, the distance between the sensor and the surface of the water, or water height, can be measured (Hajjaj et al. 2020) . ...
