Okay for learning
It works but the humidity readings seem a bit off compared to my expensive meter. Good for learning code though.

Perfect for Arduino starters
Works straight out of the box. The included wires saved me a trip to the store. Accuracy is decent for the price.

Good value but slow
Does the job for basic monitoring. Just remember it has a 1-second sampling rate so don't expect real-time rapid changes.

Reliable little sensor
I've bought five of these now. They are consistent enough for home automation triggers. Shipping was fast.

Exactly as described
Compact module and the pins are clearly labeled. Used it for a greenhouse project and it hasn't failed yet.
Q: Does it work with 3.3V logic?
A: Yes, it operates between 3V and 5V, so it is safe for 3.3V boards like ESP8266.
Q: Which library should I use?
A: The Adafruit DHT sensor library is widely recommended for Arduino IDE users.
Q: Are the wires pre-soldered?
A: No, the module comes with header pins and separate Dupont wires for easy breadboard use.
Q: Is this sensor waterproof?
A: No, the DHT11 is not waterproof. Please keep it in a dry environment.
Q: How often can I read data?
A: You should wait at least 1 second between readings to ensure data stability.
