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. Just remember it has a 1-second sampling limit.

Reliable and easy to code
Integrated this into a smart home dashboard within an hour. The data output is stable, and I haven't experienced any dropouts. Highly recommended for students and makers.

Works but slow response
The sensor functions as described, but the response time is a bit sluggish if you need rapid changes detected. For general room monitoring, it is fine.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The single-bus interface makes wiring incredibly simple, and the library support is excellent. Great value for the price.

Solid performance indoors
Using it to monitor my server room temperature. It stays consistent and alerts me when things get too warm. Just ensure you don't expose it to direct water.

Great bulk buy for classes
Bought ten of these for a workshop. Every single one worked out of the box. The breakout board design saves time on soldering resistors.
Q: Does this come with a pull-up resistor installed?
A: Yes, most breakout modules include the necessary 10kΩ pull-up resistor on the board, so you can connect it directly to your microcontroller.
Q: Is this compatible with 3.3V logic boards like the ESP8266?
A: Yes, the DHT11 operates between 3.0V and 5.5V, making it fully compatible with 3.3V systems such as the ESP8266 and ESP32.
Q: How often can I read data from this sensor?
A: The DHT11 has a sampling rate of 1Hz, meaning you should wait at least 1 second between consecutive readings to ensure accurate data.
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 within a weatherproof enclosure if used outside.
Q: What is the maximum cable length recommended for the data pin?
A: For reliable signal transmission, we recommend keeping the cable length under 20 meters. Using a pull-up resistor is also advised for longer runs.
