    Pidgin, yes. I translate this as follows:
    Connect the PCB with the electronics on it to a 5V supply
    Make sure the sensor PCB is dry. Adjust the potentiometer for a High level on the digital output (DO). The indicator LEd should be off.
    Drop some water on the sensor PCB. The digital output should be low, else adjust. The indicator LED should be on.
    The analog output can be connected to the ADC input of a microcontroller (MCU) to measure intensity of the rain.
    The digital output can be connected to a microcontroller to simply detect presence or absence of rain.

    Hope that helps,

    Harald

    Harald, I think there's a decryption position waiting for you in one of Germany's intelligence agencies. :D
