Solid performance
Fast response time when temperature changes. Only wish the PCB was slightly smaller for compact projects.

Accurate readings for home automation
Compared the output with a standard thermometer and it was within 0.5 degrees. Great value for the price point.

Good module, headers included
Solid build quality. I appreciate that the header pins were included in the package so I didn't have to solder them immediately.

Works perfectly with STM32F103
Integrated easily with my Blue Pill board. The 1-Wire protocol is straightforward to implement using HAL libraries. Readings are stable and consistent.
Q: Is this sensor waterproof out of the box?
A: No, this is a bare PCB module. For waterproof applications, you would need to house it in a sealed enclosure or use a probe version.
Q: Can I connect multiple sensors to a single GPIO pin?
A: Yes, the 1-Wire protocol supports multiple devices on the same bus using unique serial IDs for each sensor.
Q: Are there any library examples available for STM32CubeIDE?
A: Yes, there are numerous open-source repositories available that provide HAL-based drivers for the DS18B20 sensor.
Q: What is the maximum cable length for the data line?
A: Depending on the environment and pull-up resistor, you can typically achieve reliable communication up to 100 meters.
Q: Is this module safe to use with 3.3V logic levels?
A: Yes, the module operates comfortably within the 3.3V to 5.0V range, making it safe for STM32 and ESP32 logic.
