Robust and reliable
I've used these in a greenhouse monitoring system for three months now. They handle humidity well and haven't drifted in accuracy. Great value.

Best DS18B20 board I've bought
Clean PCB design and stable voltage regulation. I've tested five units from this batch, and all perform identically. Will buy again.

Solid performance
Using this for a prototype industrial monitor. It responds quickly to temperature changes. Would prefer a longer cable option, but the board itself is great.

Good accuracy, fast shipping
The sensor readings are consistent with my calibrated thermometer. The only minor issue is that the header pins were not pre-soldered, but that's expected for this price point.

Perfect for Arduino projects
This module works flawlessly with my Arduino Uno. The library support is excellent, and reading temperatures was straightforward. Highly recommended for beginners.
Q: What is the maximum cable length supported?
A: While dependent on cable quality and environment, standard practice suggests keeping cables under 50 meters for reliable 1-Wire communication without signal repeaters.
Q: Is this waterproof out of the box?
A: The PCB itself is not waterproof. If you need to use it in wet environments, we recommend applying conformal coating or placing it inside a waterproof enclosure.
Q: Does this module require an external pull-up resistor?
A: No, this development board includes an integrated 4.7kΩ pull-up resistor on the data line, so you can connect it directly to your microcontroller.
Q: Is there a Python library available for Raspberry Pi?
A: Yes, you can use the standard 'w1-gpio' kernel module built into Raspbian or use third-party libraries like 'Adafruit_CircuitPython_DS18X20' for easy integration.
Q: Can I connect multiple sensors to one pin?
A: Yes, the DS18B20 supports multi-drop capability. You can connect multiple modules to a single GPIO pin using a common power and ground, addressing each by its unique serial ID.
