  • How can I connect this?

    Impression:Not positive surprise;

    Works as it says, but the output voltage is only 1.7Volt. Sure it is fine if I wanted a LED to light up, but I wanted a water pump to switch on at 12 Volt when someone comes into the Kitchen or the bathroom. Now I have to find a relay, or make something else to switch on the 12 Volt Source to the pump. Maybe a big transistor will do the job. Some experimenting is still to come. Last time I bought something like this it had a relay and the out-voltage was the same as in.
