Essential for IoT projects
Using these with an ESP32 for a smart home greenhouse controller. The compact size fits easily into small enclosures. Very happy with the purchase, provided you have the skills to solder the sensor component yourself.

Good board, but read the title carefully
The PCB quality is excellent and the soldering points are clean. However, beginners might miss that the actual DS18B20 sensor chip is not included in the package. You need to buy that separately and solder it on. Once populated, it works perfectly with my Arduino project.

Does exactly what it says
No complaints about the hardware. It breaks out the pins nicely for breadboard use. Just remember to order the sensors separately. The 4.7k resistor value is standard and works well for most 1-wire bus lengths under 5 meters.

Confusing at first
I thought the sensor came with the module. Had to wait another week for the chips to arrive. The product description is accurate if you read it closely, but the title could be more prominent about the missing chip. The board itself seems durable though.

Perfect for custom setups
I bought ten of these to build a distributed temperature monitoring system. Having the pull-up resistor already on the board saves a lot of time. The pinout is clearly marked, making assembly straightforward.

Solid construction
Great little module. The gold plating on the contacts looks good, and the silk screen is easy to read. I soldered on some waterproof DS18B20 probes, and the connection is stable. Highly recommended for prototyping.
Q: Does this package include the DS18B20 temperature sensor chip?
A: No, this package includes only the PCB module with the necessary resistors and headers. The DS18B20 sensor chip must be purchased separately and soldered onto the board by the user.
Q: How long can the cable be if I extend the sensor away from the module?
A: For reliable communication, we recommend keeping the extension cable under 5 meters without additional shielding or lower resistance pull-ups. For longer distances, signal integrity may vary based on environmental noise.
Q: Is there a diagram showing where to solder the sensor pins?
A: Yes, the PCB has clear silk-screen markings indicating the positions for the D (Data), G (Ground), and V (Voltage) pins of the TO-92 packaged DS18B20 sensor.
Q: What is the resistance value of the on-board pull-up resistor?
A: The module comes equipped with a standard 4.7kΩ pull-up resistor connected between the VCC and DATA lines, which is required for proper 1-Wire communication.
Q: Can I use this module directly with a 3.3V microcontroller like the ESP8266?
A: Yes, the module supports an operating voltage range of 3.0V to 5.5V, making it fully compatible with both 3.3V and 5V logic microcontrollers.
