Decent but limited range
The sensor works fine, but remember the humidity range stops at 90%, so it's not ideal for very steamy environments like a bathroom. Perfect for living rooms though.

Good basic sensor
Works well for monitoring my small indoor plant setup. It's not laboratory grade, but for the cost, it does exactly what I need. The eco-friendly packaging was a nice touch.

Easy to code
I found plenty of libraries for this sensor. Connected it to my Raspberry Pi in minutes and had data logging up and running immediately. Highly recommended for learners.

Great compatibility
Tested this with both micro:bit and Arduino. The pinout is standard and the voltage tolerance makes it very flexible for different projects. Fast shipping too!

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The setup was incredibly easy, and the readings seem consistent with my room thermometer. Great value for the price.

Reliable for general use
We bought ten of these for our workshop classes. They are durable enough for students to handle and provide stable readings for most educational experiments.
Q: Is the data output analog or digital?
A: The DHT11 outputs a calibrated digital signal via a single-wire interface. You do not need an analog-to-digital converter to read the data.
Q: Does this module come with a resistor?
A: Yes, the Keyes DHT11 module includes the necessary pull-up resistor on the board, so you can connect it directly to your microcontroller without extra components.
Q: Can I use this outdoors?
A: This specific module is not waterproof. While it can tolerate some ambient outdoor conditions, we recommend placing it inside a weatherproof enclosure if used outside.
Q: What library should I use for Arduino?
A: The most popular and reliable library is 'DHT sensor library' by Adafruit. It is fully compatible with this Keyes module and available in the Arduino Library Manager.
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 and prevent communication errors.
