    Usage

    Define the LLC200D3SH sensor using the LiquidLevelSwitch class.

    using (LiquidLevelSwitch sensor = new LiquidLevelSwitch(23, PinValue.Low))
    {
        while (true)
        {
            // read liquid level switch
            Debug.WriteLine($"Detected: {sensor.IsLiquidPresent()}");
            Debug.WriteLine();
    
            Thread.Sleep(1000);
        }
    }
