Standard component done right

This is the standard DHT11 everyone uses, and this specific module has good soldering points and a clear pinout label. Highly recommended.

Good accuracy for the cost

I used this for a small greenhouse monitor. While it's not lab-grade precision, it is perfectly adequate for home automation tasks. Easy to integrate.

Great starter sensor

As someone new to electronics, I found this very easy to set up. The documentation online is plentiful. Just remember it has a 1-second sampling limit.

Works but limited range

The sensor works as advertised, but keep in mind the humidity range starts at 20%. If you need to measure very dry environments, look at the DHT22 instead.

Reliable and compact

Bought five of these for a school project. All of them worked out of the box. The single-bus interface saves GPIO pins which is a huge plus.

5 FAQ

Q: Do I need an external resistor for the data line?

A: Most modules, including this one, come with a built-in pull-up resistor on the PCB, so no external components are needed for basic operation.

Q: Which Arduino library do you recommend for this?

A: The 'DHT sensor library' by Adafruit is the most popular and well-maintained library for interfacing with this module.

Q: Can this sensor be used outdoors?

A: The sensor itself is not waterproof. If used outdoors, it must be housed in a breathable, weather-proof enclosure to protect it from rain and direct moisture.

Q: What is the maximum cable length for reliable readings?

A: For best results, keep the cable under 20 meters. Longer distances may require signal conditioning or shielding to prevent data loss.

Q: Is this compatible with 3.3V logic boards like the ESP8266?

A: Yes, the DHT11 operates between 3.3V and 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers.
