Good for indoor monitoring
I used this to monitor humidity in my small greenhouse. It's accurate enough for general tracking, though I wouldn't rely on it for scientific precision. Solid build quality.

Does the job
Integrated this into my home automation system. It's not the most precise sensor on the market, but for the cost, it provides adequate data for triggering fans or heaters.

Slow response time
The sensor works as advertised, but the 1-second sampling rate feels a bit slow if you need real-time data updates. For basic logging, it is perfectly fine.

Reliable and cheap
Bought five of these for a school project. All of them worked immediately out of the box. The single-wire interface saves a lot of GPIO pins on the microcontroller.

Great starter sensor
As someone new to electronics, this was very forgiving. Even with slightly messy wiring, it still returned consistent readings. Highly recommend for learning.

Perfect for beginner projects
This sensor works flawlessly with my Arduino Uno. The library examples made it incredibly easy to get up and running within minutes. Great value for the price.
Q: Can I use this with a 3.3V logic board like ESP32?
A: Yes, the sensor operates between 3.3V and 5V. However, ensure your data line is compatible; many modules include a pull-up resistor that works well with 3.3V systems.
Q: Is this sensor waterproof?
A: No, the DHT11 module is not waterproof. It should only be used in dry, indoor environments or protected enclosures.
Q: What is the maximum cable length recommended?
A: For reliable data transmission, we recommend keeping the cable length under 20 meters. Longer distances may require signal buffering.
Q: How often should I calibrate this sensor?
A: The DHT11 is factory calibrated and generally does not require user calibration. For critical applications, compare readings with a reference device annually.
Q: Does it come with a protective filter cover?
A: This specific package includes the bare module without an additional plastic filter cover. You may need to purchase a case separately for dust protection.
