Standard component done right
This is the standard DHT11 everyone uses, and this specific module has good soldering points and a clear pinout label. Highly recommended.

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 home automation tasks. Easy to integrate.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The wiring is straightforward, and the library support is excellent. Great value for the price.

Great starter sensor
As someone new to electronics, I found this very easy to set up. The documentation online is plentiful. Just remember it has a 1-second sampling limit.

Works but limited range
The sensor works as advertised, but keep in mind the humidity range starts at 20%. If you need to measure very dry environments, look at the DHT22 instead.

Reliable and compact
Bought five of these for a school project. All of them worked out of the box. The single-bus interface saves GPIO pins which is a huge plus.
Q: Do I need an external resistor for the data line?
A: Most modules, including this one, come with a built-in pull-up resistor on the PCB, so no external components are needed for basic operation.
Q: Which Arduino library do you recommend for this?
A: The 'DHT sensor library' by Adafruit is the most popular and well-maintained library for interfacing with this module.
Q: Can this sensor be used outdoors?
A: The sensor itself is not waterproof. If used outdoors, it must be housed in a breathable, weather-proof enclosure to protect it from rain and direct moisture.
Q: What is the maximum cable length for reliable readings?
A: For best results, keep the cable under 20 meters. Longer distances may require signal conditioning or shielding to prevent data loss.
Q: Is this compatible with 3.3V logic boards like the ESP8266?
A: Yes, the DHT11 operates between 3.3V and 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers.
