Wish it was DHT22 version
I ordered this thinking it was the higher precision model. My mistake, but the product is as described.

Perfect for Arduino Projects
Easy to wire and works immediately with the standard libraries. Great value for money.

Good sensor but slow sampling
Does the job well. Just remember there is a delay between readings. Not ideal for fast changes.

Accurate enough for home use
Compared it to my room thermometer and it was very close. Happy with the purchase.

Robust build quality
The module board is solid. The pull-up resistor is already included which saves time.
Q: Can I use this outdoors?
A: This sensor is not waterproof. It should be used in indoor or protected environments.
Q: What is the sampling rate?
A: The DHT11 has a sampling rate of 1Hz (once per second).
Q: Does it work with Raspberry Pi GPIO?
A: Yes, but ensure you use the correct GPIO pin and handle voltage levels carefully.
Q: Do I need an external resistor?
A: Most modules come with a built-in pull-up resistor. Check your specific board layout.
Q: Is this compatible with 3.3V logic boards?
A: Yes, the operating voltage range is 3.3V to 5.5V.
