If your water level sensor outputs a signal and that signal voltage is between 0V to 5V, or, if your water level sensor is a dry contact switch (i.e. does not output an active voltage, but is a reed switch or relay switch), you can connect it to OpenSprinkler as a rain sensor or soil sensor. This way, when the sensor is activated, the water programs will not run.
