Decent but slow response
The sensor works as advertised, but the 1-second sampling rate can feel slow if you need rapid changes detected. Good for general trends, not instant spikes.

Works well for plant monitoring
Using this to monitor humidity in my greenhouse. It handles the environment well, though I wish the cable was a bit longer. Overall, a solid purchase.

Essential for university projects
Bought five of these for our final year project. All units performed identically, and the data logging has been stable for weeks without any drift.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The included wires made setup incredibly easy, and the readings are consistent enough for my home weather station project.

Good value but limited range
Great sensor for the price. Just remember it's not suitable for extreme temperatures or high-precision scientific work. For basic room monitoring, it is exactly what I needed.

Plug and play simplicity
I was up and running in less than 10 minutes. The library support is excellent, and the digital output saves me from dealing with analog noise issues.
Q: How often does the sensor need calibration?
A: The DHT11 is factory calibrated and generally does not require user calibration for typical hobbyist applications. For critical industrial use, periodic verification against a reference standard is recommended.
Q: What is the maximum cable length I can extend this to?
A: While the included cable is 20cm, users typically report success extending it up to 2 meters using quality shielded cable, though signal integrity may vary beyond that.
Q: Does this come with a pull-up resistor?
A: Yes, this breakout module includes the necessary pull-up resistor on the data line, so no external components are required for basic operation.
Q: Can I use this with a 3.3V microcontroller?
A: Yes, the module operates within a voltage range of 3.3V to 5.5V, making it fully compatible with 3.3V systems like the ESP8266.
Q: Is this sensor waterproof?
A: No, the DHT11 probe is not waterproof. It should be used in dry environments or protected from direct water exposure.
