The sensor measure water depth with very good accuracy of 0 1 mbar 1 cm water level.
Water depth sensor 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.
Please read note 3 below for linear range and accuracy.
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.
Measures water pressure and depth to 30 bar 300 m 72 00 add to cart using a bar30 with most arduino including the uno mega micro and nano and other 5v microcontrollers requires an i2c logic level converter to communicate with a 3 3v device such as the bar30.
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.
The pressure module have wide range applications ranging from liquid level measurements in tanks water depth and temperature in diving snorkeling and rov.
Water sensor brick is designed for water detection which can be widely used in sensing rainfall water level and even liquid leakage.
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.
Connecting a water sensor to an arduino is a great way to detect a leak spill flood rain etc.
First you need to supply power to the sensor.
Having power applied to.
For that you can connect the vcc pin on the module to 5v on the arduino and gnd pin to ground.
