Hallo, I have exactly the same behavior on my miniD1 with just fototransistor and resistor. I get the hello messages from it but the led is on all the time....

Why? I mean BPW40 is a phototransistor and it's used at the example circuit! But I tried it with IR receiver led and different resistors. I saw 0.5 volts between...

Hi, I'm also a CUN customer with the same DD3 meter and the same problem. Have you solved it? I tired the reading head with led and transistor and just...
