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. Great value for the price.

Solid basic sensor

Does exactly what it says. The response time is a bit slow (about 2 seconds between readings), but that is expected for this model. Perfect for logging data every minute.

Reliable and easy to code

The library support for this sensor is excellent. I had it up and running in under 10 minutes. The digital output saves a lot of GPIO pins compared to analog sensors.

Great for school projects

Bought this for my final year engineering project. It survived multiple re-wirings and still works perfectly. The pre-soldered header pins are a nice touch.

Decent but limited range

Works well within its specified range. Just be careful not to use it in environments exceeding 50°C or high humidity outside 90%, as accuracy drops significantly. Good for the price point.

Good for indoor monitoring

I used this to monitor humidity in my indoor plant setup. It's accurate enough for general trends, though I know the DHT11 isn't as precise as the DHT22 for outdoor use. Still, very happy with it.

5 FAQ

Q: Is there a waterproof coating on this specific module?

A: No, this standard DHT11 module is not waterproof. It should only be used in dry, indoor environments. If you need outdoor monitoring, please look for our IP67 rated temperature sensors.

Q: How frequently can I poll this sensor for new data?

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

Q: What is the maximum cable length recommended before signal degradation occurs?

A: While the included Dupont lines are short, you can extend the wiring up to 20 meters if using shielded cable. For the standard unshielded wires provided, we recommend keeping extensions under 1 meter for stable readings.

Q: Do I need to install any specific drivers for Windows to recognize this?

A: No drivers are needed for the sensor itself. However, you will need the appropriate USB-to-Serial drivers for your microcontroller board (e.g., CH340 or CP2102) to upload the code that reads the sensor.

Q: Can this sensor be used directly with a 3.3V microcontroller like the ESP8266?

A: Yes, the DHT11 operates within a voltage range of 3V to 5.5V, making it fully compatible with 3.3V systems like the ESP8266 and ESP32 without needing a level shifter.
