Introduction to the product
The DS18B20 is a digital temperature sensor created by Dallas Semiconductor (now part of Maxim Integrated). It uses a special 1-Wire® communication protocol. This protocol allows data transfer using just a single data line, which significantly reduces the number of required connections!
You can find this sensor in two main types:
- A TO-92 package that looks like a small transistor
- A waterproof probe that’s perfect for measuring temperatures in wet environments, underground, or places that are hard to reach
