The pressure module have wide range applications ranging from liquid level measurements in tanks water depth and temperature in diving snorkeling and rov.
Water depth sensor arduino.
Solu water level sensor depth of detection water sensor for arduino high sensitivity water sensor water level sensor module depth of detection liquid surface height for arduino m.
The arduino then reads the output of the transducer and reports the depth of the tank.
In this project we will use an ethernet shield to have the arduino connect to an online datalogging service called pachube to generate graphs of water depth over time but you could also have it make decisions on the basis of the reading to control items such as a water pump or irrigation system solenoid.
The deviation with the graph can be explained with tolerances of the resistors the resistance in the sensor wire deviations in the 3 3 volt supply of the esp 32 and some non linearities in the 12.
This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator.
Let s hook the water level sensor up to the arduino.
Theoretically when the sensor is not in the water the measured value at the sensor pin is approx 1 0855 v which would be equivalent to 1347 bits.
For that you can connect the vcc pin on the module to 5v on the arduino and gnd pin to ground.
The sensor measure water depth with very good accuracy of 0 1 mbar 1 cm water level.
Having power applied to.
However one commonly known issue with these sensors is their short lifespan when exposed to a moist environment.
First you need to supply power to the sensor.
Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc.
