The Octopus DS18B20 Digital Temperature Brick uses the DS18B20 1-Wire digital temperature sensor from Maxim IC to deliver accurate readings from −55 °C to +125 °C with ±0.5 °C accuracy. Each sensor has a unique 64-bit serial number, allowing multiple sensors to share a single data bus.

Designed for the ElecFreaks Octopus:Bit ecosystem, this brick plugs directly into the P1 port and works with Microsoft MakeCode for micro:bit programming.

Key Features

• DS18B20 1-Wire Sensor – 9- to 12-bit configurable resolution
• Wide Range – −55 °C to +125 °C with ±0.5 °C accuracy
• Unique 64-Bit Serial Number – Run multiple sensors on a single data bus
• Octopus Brick Interface – 3-pin connector for easy plug-and-play wiring
• micro:bit Compatible – Programme via MakeCode with the DS18B20 package

Getting Started with micro:bit

1. Connect the brick to port P1 on your Octopus:Bit breakout board
2. In MakeCode, click Extensions and search for https://github.com/Tinkertanker/pxt-ds1820-temperature-sensor
3. Add the package and use the temperature blocks in your programme
