Accurate brewing temps
Using this to track fermentation temperatures. The response time is quick enough for my needs, and the readings match my calibrated thermometer within 0.2 degrees.

Bulk buy success
Purchased ten units for a workshop class. All of them worked out of the box. The compatibility with the D1 Mini is exactly as advertised. Highly recommended for educators.

Great for learning IoT
As a beginner, I found this module very forgiving. Plenty of tutorials online specifically mention this DS18B20 version. It connected immediately to my WiFi expansion board.

Perfect for my smart home project
This sensor works flawlessly with my D1 Mini board. The waterproof probe is a great feature for monitoring my aquarium temperature. Setup was easy using the standard OneWire library.

Reliable soil monitoring
I bought three of these to monitor soil temperature in my greenhouse. They are accurate and the long cable helps keep the electronics dry. One star off because the header pins weren't pre-soldered.

Good sensor, short cable
The sensor itself is high quality and reads accurately. However, the 20cm cable was too short for my specific enclosure setup, so I had to extend it myself. Otherwise, it works well.
Q: Can I connect multiple sensors to a single GPIO pin?
A: Yes, the DS18B20 uses a 1-Wire protocol which allows you to daisy-chain multiple sensors on the same data line. Each sensor has a unique 64-bit serial code, allowing the microcontroller to address them individually.
Q: Does this module require an external pull-up resistor?
A: Most breakout boards for the DS18B20 include an onboard 4.7kΩ pull-up resistor. You can verify this by checking for a resistor marked '472' near the data pin on your specific board. If present, no external resistor is needed.
Q: What is the maximum update rate for temperature readings?
A: The conversion time depends on the resolution setting. At 12-bit resolution (highest accuracy), a conversion takes approximately 750ms. You can reduce this time by lowering the resolution to 9, 10, or 11 bits.
Q: Is the probe truly waterproof for submersion?
A: The stainless steel probe tip is designed to be waterproof and can be submerged in liquids. However, please ensure the junction where the cable meets the probe and the USB/electronic end remain dry unless specifically sealed by you.
Q: What library should I use for the D1 Mini?
A: For the D1 Mini (ESP8266), we recommend using the 'OneWire' library combined with the 'DallasTemperature' library. Both are available in the Arduino IDE Library Manager and are fully compatible.
