Solid budget option
We bought ten of these for our workshop. Most work perfectly out of the box. One had a slightly loose pin, but we fixed it easily. Good bulk buy for education.

Perfect for Arduino beginners
This module works flawlessly with my Arduino Uno. The included Dupont lines made connection super easy, and the indicator light helps confirm power is on. Great value for the price.

Decent but limited range
Works as described, but keep in mind the humidity range starts at 20%. If you need to measure very dry environments, look elsewhere. Otherwise, it's a solid little sensor.

Reliable and fast shipping
Arrived quickly and well-packaged. The sensor responds instantly to changes in breath humidity during testing. The digital output is stable and noise-free.

Good for basic monitoring
I use this to monitor humidity in my small greenhouse setup. It's not lab-grade accurate, but for the cost, it gives me a good general idea of the conditions. Easy to code for.

Great for school projects
Bought this for a university IoT project. The library support is excellent, and I had it up and running in minutes. The indicator light is a nice touch for debugging.
Q: What is the length of the included Dupont lines?
A: The included Dupont jumper wires are approximately 20cm (8 inches) long, suitable for breadboard connections.
Q: Does it require an external resistor?
A: No, this breakout module already includes the necessary pull-up resistor on the board, so you can connect it directly to your microcontroller.
Q: How often can I read data from the sensor?
A: The DHT11 has a sampling rate of 1Hz, meaning you should wait at least 1 second between readings to ensure accurate data retrieval.
Q: Can this sensor be used outdoors?
A: The module itself is not waterproof. For outdoor use, you must house it in a weatherproof enclosure while ensuring air can reach the sensor vents.
Q: Is this compatible with Raspberry Pi?
A: Yes, the DHT11 module is fully compatible with Raspberry Pi models using Python libraries like Adafruit_DHT or CircuitPython.
