Good enough for indoor monitoring
I used this to monitor humidity in my plant room. It's not laboratory grade, but for general home automation, it does the job well.

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 for school projects
Bought this for a university sensor network project. It was easy to set up, though the response time is a bit slow compared to newer sensors like the DHT22.

Decent but limited range
Works fine indoors, but keep in mind the temperature limit stops at 50°C. If you need higher ranges, look elsewhere. Otherwise, solid performance.

Bulk buy success
Purchased ten of these for our workshop. All of them worked out of the box. The breakout board saves a lot of time soldering headers.

Reliable digital output
The single-bus communication makes it very easy to interface. I've tested three units, and they all returned consistent readings within the expected tolerance.
Q: Which Arduino library works best with this module?
A: The standard 'DHT sensor library' by Adafruit is widely used and highly recommended for interfacing with this module.
Q: Does this come with a resistor already installed on the data line?
A: Most modules include a pull-up resistor on the PCB. However, if your specific board does not, you may need to add a 10k ohm resistor between VCC and the data pin.
Q: Can I use this outdoors in the rain?
A: No, this sensor is not waterproof. It should be housed in a ventilated but weather-proof enclosure if used outdoors.
Q: What is the maximum cable length recommended for the sensor?
A: For reliable digital signal transmission, we recommend keeping the cable length under 20 meters. Longer distances may require signal buffering.
Q: Is this compatible with 3.3V logic boards like the ESP8266?
A: Yes, the DHT11 operates between 3.3V and 5V, making it fully compatible with both 3.3V and 5V microcontrollers.
