Measure Temperature with a Sensor Made for Embedded Builds
The Temperature Sensor Waterproof DS18B20 kit is a temperature sensor with 1-wire designed for temperature logging, thermal control, and equipment monitoring. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Usable temperature range: -55 to 125°C (-67°F to +257°F); Operating voltage: 3.0~ 5.5V; Interface: 1-Wire.
Important: Sensor response time depends on airflow, mounting, and thermal contact. Keep heat sources and self-heating from nearby parts in mind.

Frequently Asked Questions
What does the Temperature Sensor Waterproof DS18B20 kit measure?
It is designed to measure temperature.
Can I use it with Arduino, ESP32, or Raspberry Pi?
Yes. It is well suited for common maker and embedded platforms, as long as you power it at the correct voltage and match the signal level to your controller.
How do I connect this 1-Wire sensor?
This version uses a 1-Wire data line and usually needs a pull-up resistor on the data pin.
What affects accuracy?
Power quality, wiring, mounting, target material, and the real environment can all affect the reading. It is best to test and calibrate in the final setup.
Is it good for prototyping?
Yes. It is a practical choice for learning, proof-of-concept builds, and small automation projects.
