Solid sensor module
Does exactly what it says. The waterproof probe version would have been nicer for my specific application, but this bare board module is great for indoor electronics.

Good value, easy to use
Bought this for a DIY greenhouse monitor. It's very responsive. The only reason for 4 stars instead of 5 is that the header pins were slightly loose, but a quick solder fixed it.

Fast shipping and great quality
Arrived earlier than expected. The PCB quality looks professional with clear silkscreen markings. Integration with ESPHome was seamless.

Great for learning embedded systems
Using this in my university project. The 1-wire protocol is fascinating to learn, and this board makes prototyping incredibly fast. Highly recommend for students.

Reliable batch purchase
Ordered ten of these for our makerspace. All units tested perfectly out of the box. Consistent performance across the board. Will order again.

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.
Q: Is a pull-up resistor already included on the board?
A: Yes, this development board typically includes a built-in 4.7kΩ pull-up resistor between the VCC and Data lines, so you can connect it directly to your microcontroller without extra components.
Q: What is the maximum cable length recommended for the data line?
A: While the 1-Wire protocol can theoretically support longer distances, we recommend keeping the cable length under 100 meters for reliable communication. For longer runs, shielded cable and lower baud rates may be necessary.
Q: What library do you recommend for using this with Arduino?
A: We recommend the standard 'DallasTemperature' library used in conjunction with the 'OneWire' library. Both are widely available in the Arduino Library Manager and work perfectly with this module.
Q: Can I connect multiple of these sensors to a single GPIO pin?
A: Yes, the DS18B20 supports multi-drop capability via the 1-Wire protocol. You can connect multiple sensors to the same data line, provided you use a unique address for each and have an appropriate pull-up resistor.
Q: Does this module come with a waterproof probe attached?
A: No, this listing is for the bare DS18B20 module board only. It does not include a waterproof steel probe or extended cable. You can connect your own external probe to the data pin if needed.
