Perfect for beginner projects

This DHT11 module works flawlessly with my Arduino Uno. The included Dupont lines made connection incredibly easy without needing a breadboard immediately. Readings are consistent for basic home monitoring.

Good value but limited range

Does exactly what it says for the price. Keep in mind the humidity range starts at 20%, so it might not be ideal for very dry environments. Otherwise, great for my indoor plant setup.

Solid basic sensor

Using it to trigger a fan when humidity gets too high in the bathroom. It's not industrial grade, but for hobbyist automation, it hits the sweet spot between price and performance.

Works but slow update rate

The sensor is accurate enough for general use, but remember it only updates once per second. If you need rapid changes detected, look at the DHT22 instead. Still, good for the cost.

Reliable and easy to code

Integrated this into an ESP32 weather station. The library support is excellent, and the sensor responds quickly. The pre-soldered header pins are a nice touch.

Great for school projects

Bought this for a university IoT assignment. It paired instantly with the Raspberry Pi and the data logging was straightforward. Highly recommend for students on a budget.

5 FAQ

Q: Can this sensor be used directly with 5V logic?

A: Yes, the DHT11 module operates comfortably between 3.3V and 5.5V, making it compatible with both 3.3V and 5V microcontrollers like Arduino and ESP boards.

Q: What is the length of the included Dupont lines?

A: The included female-to-female Dupont jumper wires are approximately 20cm (8 inches) long, which is standard for most breadboard and prototype connections.

Q: Do I need an external resistor for this module?

A: No external resistor is needed. This breakout board already includes the necessary pull-up resistor on the PCB, allowing you to connect it directly to your microcontroller.

Q: How accurate is the temperature reading compared to a thermometer?

A: The DHT11 has a typical accuracy of ±2°C. While sufficient for general environmental monitoring, it may show slight variances compared to high-precision laboratory thermometers.

Q: Is this sensor waterproof?

A: No, the DHT11 sensor is not waterproof. It should only be used in dry indoor environments or protected enclosures to prevent damage from moisture or direct water contact.
