Solid build quality

The PCB looks professional and the soldering is clean. It handles the 5V logic level perfectly without needing extra level shifters for my specific setup.

Great for university labs

Purchased for a senior design project. The response time is quick, and the resolution settings are easy to adjust via code. Exactly what we needed for our data logging system.

Good value, clear documentation

Great little sensor for the price. The pinout is clearly marked. I deducted one star because the included header pins were slightly bent, but nothing a quick fix couldn't solve.

Perfect for STM32 projects

This module worked flawlessly with my STM32F103 board. The 1-wire protocol was easy to implement, and the temperature readings were accurate compared to my calibrated thermometer.

Works well for plant monitoring

Using this to monitor soil temperature in my greenhouse. It's waterproof enough for ambient humidity, though I added extra protection for direct water contact. Readings are stable.

Reliable and fast shipping

I bought three of these for a home automation project. All three sensors gave consistent readings right out of the box. Highly recommended for beginners and pros alike.

5 FAQ

Q: Is the sensor probe detachable from the board?

A: No, the DS18B20 sensor is soldered directly onto the PCB for durability and compactness. It is not designed to be detached.

Q: Does this come with example code for STM32 HAL?

A: Yes, you can find example code for STM32 HAL in the 'Documents' section of the product page or by contacting our support team directly.

Q: Is this module compatible with Arduino boards as well?

A: Yes, the DS18B20 sensor on this module is fully compatible with Arduino boards using the standard 1-Wire library.

Q: What is the maximum cable length recommended for the sensor?

A: For reliable communication, we recommend keeping the cable length under 50 meters. Using a shielded twisted pair cable can help reduce noise interference.

Q: Can I power this directly from a 3.3V pin?

A: Absolutely. The module operates within a 3.3V to 5V range, so connecting it to a 3.3V power source is safe and effective.
