DHT11 sensor, it didn't show on serial monitor

GolamMostafa:
Check the continuity of the jumper wires. Also, try to make direct jumper on the pins of the sensors instead of through breadboard holes.

Totally working, 5v wire which I was using was broken. I'm sorry to ask this topics but for me it was very strange this error.

Now it's working fine

Thank you so much GolamMostafa :slight_smile:
