Description
A pair of DS18B20 digital temperature sensors in a compact TO-92 package.
These reliable sensors communicate via a single 1 Wire data bus and support power through the data line (“parasite power”), making them ideal for Arduino, Raspberry Pi, and other microcontroller applications.
Each sensor includes a unique 64-bit serial code, enabling multiple sensors on a single bus perfect for scalable temperature sensing projects.
