Reliable and easy to code
Bought five of these for a classroom setup. All of them worked immediately out of the box. The digital output eliminates the need for extra analog-to-digital conversion logic.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The single-bus interface makes wiring incredibly simple, and the included library examples got me up and running in minutes. Great value for the price.

Great starter sensor
As someone new to electronics, I found this module very forgiving. The pins are clearly labeled, and it survived a few accidental reverse polarity connections without burning out.

Works but slow response
The sensor functions as described, but be aware that it cannot take readings faster than once per second. If your project requires rapid data logging, you might need the DHT22 instead.

Solid basic sensor
Integrated this into a smart home dashboard. It provides consistent readings for living room conditions. The plastic housing feels a bit light, but it gets the job done indoors.

Good accuracy for the cost
I used this for a small greenhouse monitor. While it's not lab-grade precision, it is perfectly adequate for general environmental monitoring. Just remember it has a 1-second sampling limit.
Q: What is the maximum cable length recommended for the data pin?
A: For reliable communication, we recommend keeping the cable length under 20 meters. Longer distances may require a pull-up resistor adjustment or signal buffering.
Q: Is this compatible with 3.3V logic boards like the ESP8266?
A: Yes, the DHT11 operates between 3V and 5.5V, making it fully compatible with 3.3V systems such as the ESP8266 and ESP32 without needing a level shifter.
Q: Which library works best for reading this sensor?
A: The standard 'DHT sensor library' by Adafruit is widely supported and works excellently with this module on both Arduino and PlatformIO environments.
Q: Does this come with a protective filter cap?
A: This specific module version typically does not include a white sintered filter cap. It is designed for indoor use where dust and direct water exposure are minimal.
Q: Can I use this outdoors in the rain?
A: No, the DHT11 is not waterproof. It should only be used in dry, indoor environments or inside a weatherproof enclosure if used outside.
