Good value, standard accuracy

Works well for general indoor monitoring. Keep in mind this is the DHT11, not the higher precision DHT22, so don't expect laboratory-grade data. For the price, it's a solid choice for learning.

Plug and play simplicity

I was up and running within minutes of unboxing. The digital output saves a lot of GPIO pins compared to analog sensors. Great little component for home automation prototypes.

Great for plant monitoring

Using this to monitor humidity in my greenhouse setup. It handles the environment well, though I wish the humidity range went lower for dry storage applications. Still, highly recommended for plants.

Perfect for Arduino beginners

This module is exactly what I needed for my weather station project. The included Dupont wires made connection incredibly easy, and the indicator light confirms power status immediately. Readings are consistent with my other sensors.

Works perfectly with Python

Connected this to my Raspberry Pi Zero using the Adafruit library. No issues with signal noise or dropped readings. The indicator light is a nice touch for troubleshooting connections.

Reliable for school projects

Bought five of these for our university robotics club. All of them worked flawlessly out of the box. The build quality feels sturdy enough for repeated prototyping.

5 FAQ

Q: Is this compatible with ESP8266 NodeMCU boards?

A: Yes, the DHT11 module operates at 3.3V to 5V, making it fully compatible with ESP8266 and ESP32 development boards.

Q: How often can I read data from this sensor?

A: The DHT11 has a sampling rate of 1Hz, meaning you should wait at least 1 second between consecutive readings to ensure accurate data.

Q: Does this require an external pull-up resistor?

A: Most versions of this module include an onboard pull-up resistor, so you can connect it directly to your microcontroller without additional components.

Q: Can this sensor be used outdoors in the rain?

A: No, this module is not waterproof. It should only be used in dry, indoor environments or inside a protective enclosure if used outdoors.

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

A: The included Dupont jumper wires are approximately 20cm (8 inches) long, suitable for breadboard prototyping.
