Good basic sensor
Does exactly what it says. The humidity reading is decent for indoor monitoring, though not lab-grade precision. Perfect for home automation prototypes.

Fast shipping, works great
Arrived well-packaged. The PCB looks clean, and the soldering points are solid. Tested against a calibrated thermometer and it was within the stated accuracy range.

Solid performance for the cost
I bought five of these for different rooms. They all perform consistently. Just remember it's not suitable for extreme temperatures, but for room temp, it's excellent.

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

Great starter kit component
As someone new to electronics, having the jumper wires included was a huge plus. The module is clearly labeled, and I got readings within minutes of plugging it in.
Q: Are the Dupont lines male-to-female or female-to-female?
A: The included Dupont lines are Female-to-Female, which allows you to connect the module directly to most microcontroller boards like Arduino or Raspberry Pi GPIO pins without additional adapters.
Q: Can this sensor be used outdoors?
A: While the module can function outdoors if protected from direct rain and sunlight, the DHT11 is primarily designed for indoor use. For harsh outdoor environments, we recommend the DHT22 model which has a wider range and better durability.
Q: What is the maximum cable length I can use?
A: For reliable digital signal transmission with the DHT11, we recommend keeping the cable length under 20 meters. If you need longer distances, consider adding a pull-up resistor closer to the sensor end.
Q: Is a library required for Arduino?
A: Yes, but it is very easy to install. You can search for 'DHT sensor library by Adafruit' in the Arduino Library Manager. It simplifies the code significantly and handles the timing requirements automatically.
Q: Does this work with 3.3V logic levels?
A: Yes, the module operates comfortably between 3.3V and 5.5V, making it fully compatible with both 3.3V systems like ESP8266/ESP32 and 5V systems like Arduino Uno.
