Solid performance
Using this for a home brewing temperature logger. The accuracy is sufficient for my needs. The only minor issue is that the cable included was a bit short, but that's easily solved.

Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The wiring is straightforward, and the library support is excellent. Readings are stable and accurate compared to my calibrated thermometer.

Reliable and Robust
I've used these in several greenhouse monitoring systems. They handle humidity well and the digital output eliminates noise issues common with analog sensors. Highly recommended for IoT builds.

Essential component
Bought five of these for a multi-zone heating control system. All units performed identically, which is crucial for my application. The breakout board design makes prototyping much faster.

Good value, fast shipping
Great little sensor for the price. It took a few minutes to get the code right, but once configured, it provides consistent temperature data. Would have given 5 stars if the header pins were pre-soldered.

Easy for beginners
As someone new to electronics, I found this very easy to set up. There are plenty of tutorials online specifically for this board. It responded immediately upon uploading the sample code.
Q: Does this module come with waterproofing for outdoor use?
A: The standard module itself is not waterproof. However, the DS18B20 sensor probe versions are available separately with stainless steel waterproof casing. For this breakout board, you would need to add your own enclosure for outdoor protection.
Q: How long is the response time for a temperature change?
A: The conversion time depends on the resolution setting. At the default 12-bit resolution, it takes approximately 750ms to complete a temperature conversion. Lower resolutions result in faster read times.
Q: What library do you recommend for ESP32?
A: For ESP32, the 'OneWire' library combined with 'DallasTemperature' is the industry standard and works perfectly with this module. Both are available directly in the Arduino IDE Library Manager.
Q: Can I connect multiple sensors to a single GPIO pin?
A: Yes, the DS18B20 supports multi-drop capability via the 1-Wire protocol. You can connect multiple modules to the same data line, provided you use a suitable pull-up resistor and address each sensor uniquely in your code.
Q: Is the 3.3V logic level safe for Raspberry Pi?
A: Yes, this module operates comfortably within the 3.0V to 5.5V range, making it fully compatible with the Raspberry Pi's 3.3V GPIO logic levels without needing a level shifter.
