Good enough for basic monitoring

I use this to monitor humidity in my small greenhouse. It's not lab-grade precision, but for the cost, it gives me a good idea of when I need to water or ventilate.

Limited range but cheap

It works well within its specified range, but don't expect it to handle extreme conditions. For indoor room temperature checks, it is perfectly adequate.

Perfect for beginner Arduino projects

This DHT11 sensor works exactly as described. It was very easy to connect to my Arduino Uno and the library examples worked immediately. Great value for the price.

Reliable budget sensor

Bought five of these for different rooms. They all provide consistent readings relative to each other. Excellent choice for prototyping.

Solid performance

The response time is decent, usually updating within a couple of seconds. Just remember it has a 1-second sampling limit so don't poll it too fast.

5 FAQ

Q: How long is the cable included?

A: This item is sold as a bare module or header-pin version and does not include an extension cable. You can easily solder your own wires to extend the connection.

Q: Does this come with a pull-up resistor?

A: Most modules including this one come with a built-in pull-up resistor on the data line, making it ready to use without additional components.

Q: Can I use this with a Raspberry Pi?

A: Yes, the DHT11 is fully compatible with Raspberry Pi models. You will need to install a Python library like Adafruit_DHT to read the data.

Q: Is this sensor waterproof?

A: No, the DHT11 is not waterproof. It should only be used in dry environments or enclosed in a protective housing if used in areas with high moisture risk.

Q: What is the difference between DHT11 and DHT22?

A: The DHT22 offers a wider temperature and humidity range with better accuracy compared to the DHT11. However, the DHT11 is more affordable and sufficient for basic indoor projects.
