I have a DHT11 module that looks exactly like the image below. I also have raspberry pi zero wh.

  • I have connected 3.3V (pin1) to the + on the module.
  • GND (pin6) to the - on the module.
  • I was carefull never to connect anything to 5V

Unfortunately this stops my raspberry from turning on. It doesn't matter if I connect the data cable or not. As soon as those two are connected the power led does turn off. If I try to connect them while the raspberry is on it immediately shuts off. (power led goes off, ssh connection is lost) Am I doing something wrong, or do I maybe have a faulty sensor module here? How do I even start to check for that?

Answer

As per the comments of @joan and @theashwwanisingla I tested the module/sensor and there is 0 resistance between the + and - pins. So this is simply a broken piece of hardware.
