Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The included Dupont lines made connection instant without any soldering. Great value for the price.

Works as described
No issues with functionality. The readings match my standalone thermometer reasonably well. Just remember it has a limited range compared to the DHT22.

Good for basic monitoring
I used this to monitor humidity in my small greenhouse. It's accurate enough for general trends, though don't expect laboratory precision. Easy to set up.

Slow response time
The sensor works, but the 1-second sampling rate feels a bit slow when you need rapid updates. For static room monitoring, it is perfectly fine.

Reliable and cheap
Bought five of these for a school project. All of them worked out of the box. The library support for ESP32 is excellent. Highly recommended for students.

Great starter sensor
If you are just getting into IoT, this is the sensor to start with. Simple wiring, plenty of tutorials online, and the dupont wires are a nice touch.
Q: Does this module work 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 boards like the ESP8266 and ESP32 without needing a level shifter.
Q: Do I need to install a resistor for this to work?
A: Most breakout modules, including this one, already have the necessary pull-up resistor soldered on the board, so no external resistor is required.
Q: Can I use this outdoors in the rain?
A: No, the DHT11 module is not waterproof or weatherproof. It should only be used indoors or inside a protective enclosure if used outside.
Q: Is there a difference between this and the DHT22 sensor?
A: Yes, the DHT22 offers higher accuracy and a wider temperature/humidity range, but the DHT11 is faster and more cost-effective for basic applications.
Q: What is the length of the included Dupont lines?
A: The included female-to-female Dupont jumper wires are approximately 20cm (8 inches) long, which is ideal for breadboard prototyping.
