Good module, slow update rate
The hardware quality is fine, but remember DHT11 has a 2-second sampling limit. Not suitable for rapid temperature change detection. My fault for not checking specs closer.

Great for school projects
Easy to connect to Arduino Uno. The documentation provided by the seller was clear. Got it working in under 10 minutes.

Plug and play simplicity
Exactly what I needed for a weather station. The TX/RX pins are clearly labeled. Soldering points are generous and easy to work with.

Reliable but DHT11 is basic
Works well for general monitoring. Keep in mind the DHT11 sensor itself isn't very precise, but the module circuitry is solid. Would recommend upgrading to a pure DS18B20 setup for critical temps.

Stable voltage regulation
I appreciate the onboard regulator. I can feed it 5V directly without worrying about damaging the sensor logic. Data stream is consistent.

Perfect for quick prototyping
This module saved me hours of wiring. The serial output works flawlessly with my ESP32 project. No need for complex libraries, just read the UART stream.
Q: What is the default baud rate for the serial output?
A: The default baud rate is 9600 bps, 8 data bits, no parity, and 1 stop bit (9600-8-N-1).
Q: How do I change the temperature unit from Celsius to Fahrenheit?
A: The module outputs raw data or pre-formatted strings depending on the firmware version. Most users convert the value in their microcontroller code, but some versions accept a command string 'UNIT:F' via serial to switch modes.
Q: Does this module support both sensors simultaneously?
A: No, this specific board is designed to interface with either a DHT11 or a DS18B20 sensor depending on the jumper setting or specific model variant purchased. Please check the product images for the installed sensor type.
Q: Can I use this with a 3.3V microcontroller like ESP8266?
A: Yes, the module operates within a 3.3V to 5.5V range, making it fully compatible with 3.3V logic systems like the ESP8266 and ESP32.
Q: Is the waterproof probe included?
A: This listing is for the bare module only. If you require the stainless steel waterproof DS18B20 probe, please select the bundle option or purchase the probe separately.
