The DHT22 sensor does not take readings. What to do?

Question

Arduino

There is an Arduino Uno, and a DHT22 sensor. I'm using the dht and Adafruit Unified Sensor libraries to output temperature and humidity readings. But I get the error "Failed to read from DHT sensor!
". I am attaching a photo of the circuit, I used an example of the dhtTester program. What am I doing wrong and how to solve this problem?

Answer 1

In my opinion, one of the wires should be plugged into GND (always should, the ground is always common), and the other into 5V.
Your circuit cannot work in principle - the sensor has no power.
