Does the job perfectly
No issues with connectivity or data consistency. I am using three of these in different rooms and they all report consistent relative values. Highly recommended for beginners.

Great for learning sensors
Bought this for a university project. The documentation online is plentiful, which helped me debug my code quickly. Just remember it has a slow sampling rate compared to newer models.

Reliable and compact
The form factor is tiny, making it easy to fit into custom 3D printed enclosures. I've tested it against a more expensive sensor and the variance is negligible for hobby use.

Decent but limited range
It works well within the specified range, but keep in mind it struggles below 0°C or above 50°C. For indoor climate control, it is sufficient, but look at the DHT22 for wider ranges.

Perfect for beginner Arduino projects
This DHT11 module works exactly as described. It was very easy to connect to my Arduino Uno using the standard library. The readings are stable enough for basic home monitoring.

Good value for the price
I bought this to monitor humidity in my small greenhouse. While it isn't laboratory grade, it gives me a good general idea of the conditions. Setup took less than 10 minutes.
Q: Does this module come with a protective cover?
A: This specific listing includes the bare module with the white plastic grid cover typical of DHT11 sensors. It protects the internal sensing element from dust while allowing air flow.
Q: Can I use long wires to extend the sensor distance?
A: While possible, we recommend keeping the wire length under 20 meters to prevent signal degradation. Using a shielded cable and a strong pull-up resistor can help with longer distances.
Q: What is the difference between this DHT11 and the DHT22?
A: The DHT22 offers higher accuracy and a wider temperature and humidity range compared to the DHT11. However, the DHT11 is generally faster and more cost-effective for basic indoor applications.
Q: Is this compatible with Raspberry Pi GPIO pins?
A: Yes, the DHT11 is fully compatible with Raspberry Pi. You will need to connect the data pin to a GPIO pin and ensure you have a pull-up resistor if your breakout board does not include one.
Q: Is there a library available for ESP32?
A: Yes, the DHT11 is supported by the popular Adafruit DHT library and the standard ESP32 DHT libraries available in the Arduino IDE and PlatformIO.
