Essential for home automation
Integrated this into my smart home setup to monitor water tank temperature. The signal remains strong even with a 5-meter extension cable added. Very satisfied with the performance.

Perfect for Arduino Projects
This adapter board made connecting the DS18B20 probe to my Arduino Uno incredibly easy. The pinout is clearly labeled, and the readings are stable and accurate. Highly recommended for beginners.

Reliable and Fast Shipping
The sensor responds quickly to temperature changes. I tested it against a calibrated thermometer, and the deviation was negligible. The adapter board saves so much time compared to breadboarding.

Great value for money
I bought three of these for a greenhouse monitoring system. They all worked out of the box with my ESP32. The waterproofing on the probe seems robust against humidity.

Good for learning embedded systems
Using this for my university project on IoT. The documentation provided by the seller helped me get started with the OneWire library quickly. Works as described.

Solid build quality
Used this for a small industrial monitoring prototype. The stainless steel probe feels durable, and the board handles the 1-wire protocol without issues. Only wish the cable was a bit longer.
Q: Is the probe tip safe for measuring food temperatures?
A: While the stainless steel probe is generally food-grade, this product is sold as an electronic development component. We recommend verifying specific food safety certifications before using it in direct contact with consumables.
Q: What is the maximum length I can extend the wire?
A: The standard 1-wire bus can typically support up to 100 meters depending on cable quality and environment. For longer distances, we recommend using shielded twisted pair cable and ensuring a strong pull-up resistor.
Q: Does this board require an external pull-up resistor?
A: Yes, the DS18B20 protocol requires a 4.7kΩ pull-up resistor between the data line and VCC. Some adapter boards include this onboard; please check the specific schematic image in the gallery or add one externally if not present.
Q: Do you provide sample code for Raspberry Pi?
A: Yes, we provide a link in the product description to a GitHub repository containing Python scripts for Raspberry Pi and C++ examples for Arduino to help you get started immediately.
Q: Can I use this sensor directly with 3.3V logic like ESP8266?
A: Absolutely. The DS18B20 operates within a voltage range of 3.0V to 5.5V, making it fully compatible with 3.3V microcontrollers like the ESP8266 and ESP32 without needing level shifters.
