Reliable but needs calibration note
Works great for monitoring my indoor garden. The humidity readings are consistent. Note that DHT11 is less accurate than DHT22, but for this price point, it's exactly what I needed.

Great for university projects
Bought this for my final year IoT project. The documentation provided by the seller was clear, and the baud rate was easy to configure. Highly recommend for students.

Good value, slow update rate
The sensor works as advertised, but remember the DHT11 has a slow sampling rate (once every 2 seconds). If you need real-time rapid changes, look at other options. Otherwise, it's fine.

Solid build quality
The PCB looks professional and the soldering is clean. It handles the voltage fluctuations from my power supply well. Only wish it came with a waterproof probe option for outdoor use.

Perfect for quick prototyping
This module saved me hours of wiring. The serial output works flawlessly with my ESP32 without needing extra libraries for the sensor itself. Just read the UART stream and parse the data.

Plug and play simplicity
No complex I2C addressing issues. Since it outputs serial data directly, I can connect it to any microcontroller with a UART port. Very convenient for legacy systems too.
Q: Can this module work directly with a Raspberry Pi GPIO?
A: Yes, but you must connect the TX pin of the module to the RX pin (GPIO 15) of the Raspberry Pi. Ensure you enable the UART interface in raspi-config and use a logic level shifter if your Pi is 3.3V only and the module is set to 5V.
Q: What is the default baud rate for the serial communication?
A: The factory default baud rate is 9600 bps. Some versions allow changing this via specific command strings, but 9600 is standard for immediate plug-and-play usage.
Q: What format does the data string come in?
A: The data is usually sent as a simple ASCII string, often formatted like 'T:25.5,H:60' or similar, depending on the firmware version. This makes parsing easy in Python, C++, or Node.js.
Q: Is the sensor waterproof for outdoor soil monitoring?
A: The electronic module itself is not waterproof. However, if you select the version with the DS18B20 stainless steel probe, that specific probe is waterproof and suitable for soil or liquid immersion, while the main board should remain dry.
Q: Does this support both DHT11 and DS18B20 simultaneously?
A: No, each module is typically populated with either a DHT11 (for temp + humidity) or a DS18B20 (for high-precision temperature only) sensor. Please check the specific product variant title before ordering.
