Good value for indoor monitoring
I used this to monitor humidity in my small greenhouse. It's accurate enough for general trends, though not precise enough for scientific experiments. Great price point.

Perfect for beginner projects
This DHT11 module works flawlessly with my Arduino Uno. The indicator light is a nice touch to confirm power connection. Setup was easy using standard libraries.

Decent but limited range
It works well for basic needs, but keep in mind the humidity accuracy drops outside the 20-90% range. For the price, it's still a solid choice for education.

Works as expected
Bought this for a university sensor network project. Data readings are consistent. Just remember the sampling rate is limited to once per second.

Reliable and compact
The form factor is very small, making it easy to fit into tight enclosures. The single-wire interface saves GPIO pins on my ESP32 project. Highly recommended.
Q: How long is the cable included with the module?
A: This item is typically sold as a bare board module without attached cables to allow for custom wiring lengths, but header pins are usually included for easy breadboard use.
Q: Is this module compatible with 3.3V logic levels?
A: Yes, the DHT11 module operates between 3.3V and 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers.
Q: Does the indicator light stay on all the time?
A: Yes, the built-in LED indicates power status and will remain lit as long as the module is receiving voltage.
Q: Can this sensor be used outdoors?
A: While it can function outdoors, the DHT11 is not waterproof or dustproof. We recommend placing it inside a ventilated protective enclosure if used outside.
Q: What library should I use for Arduino?
A: The most popular library is 'DHT sensor library' by Adafruit, which is available directly in the Arduino Library Manager.
