I can clearly see the voltages on sensor leads but I am looking for any examples for reading the hi low values with python. Is it an I2C device ?

Engineering support team from supplier has advised that this LL sensor is a digital device, the output is high or low, depending on if it is in contact with water or not. No matter what system is used as the interface,
it would be up to the end user to write the simple code or work with their own interface to simply read if the digital input is high or low (1 or 0).
