Octopus DS18B20 Digital Temperature Brick

Octopus Electronic Bricks! You can use them build electronics projects just as easy as piling bricks! By using Octopus electronic bricks, you may connect Arduino or compatible boards easily with various digital, analog and I2C/Uart interfaces. These breadboard-less firm connections includes an extensive collection of modules like potentiometers, sensors, relays, servos, and even buttons.  Just plug and play!

This brick uses the DS18B20 1-Wire digital temperature sensor from Maxim IC. It can report degrees Celcius with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it that can allow for a huge number of sensors to be used on one data bus.
