Reliable and cheap
Bought five of these for a school project. All of them worked immediately without any calibration needed. The response time is decent for a sensor in this price range.

Solid basic sensor
We use these in our workshop for environmental monitoring. They aren't lab-grade precision instruments, but for the cost, they provide consistent and usable data for our needs.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The library examples made it incredibly easy to get temperature and humidity readings within minutes of unboxing. Great value for the price.

Works but slow sampling
The sensor functions as described, but remember it has a 1-second sampling period. If you need rapid data logging, this might not be the best choice. For static displays, it is fine.

Good for indoor monitoring
I used this to monitor my indoor plant setup. It's accurate enough for general purposes, though I noticed it struggles a bit if the humidity drops below 20%. For typical room conditions, it is excellent.

Easy to wire up
As someone new to electronics, I appreciated that the pins are clearly labeled on the board. Connected it to my ESP32 and had data showing on my phone instantly. Highly recommended for beginners.
Q: Does this work with 3.3V logic levels?
A: Yes, the module operates between 3.3V and 5.5V, making it compatible with both 3.3V and 5V microcontrollers like the ESP8266 and Arduino.
Q: Can this sensor be used outdoors in the rain?
A: No, the DHT11 module is not waterproof. It should only be used in dry, indoor environments or housed in a protective enclosure if used outside.
Q: Why is my humidity reading stuck at 99%?
A: This usually indicates a wiring issue or a missing pull-up resistor. Please check your connections and ensure a 10k ohm resistor is connected between the data pin and VCC.
Q: What is the maximum cable length recommended?
A: For reliable data transmission, we recommend keeping the cable length under 20 meters. Longer distances may require a pull-up resistor adjustment or signal buffering.
Q: Is a separate library required for Arduino?
A: While you can write your own code, we recommend using the popular 'DHT sensor library' by Adafruit available in the Arduino Library Manager for the easiest integration.
