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
- Connect the brick to port P1 on your Octopus:Bit breakout board
- In MakeCode, click Extensions and search for

Ideal For
- micro:bit weather stations and environmental monitoring
- Arduino temperature logging projects
- Multi-sensor 1-Wire networks
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- 1-Wire
- 1-Wire is a communication method where devices share a single data line, often with each device having its own address. It matters because several temperature modules can be connected to one microcontroller pin instead of needing a separate pin for each probe.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- DS18B20
- A common digital temperature sensor often sold in waterproof probe form. It matters here because the kit does not include temperature measurement, and a DS18B20 is the suggested add-on if your water readings need temperature context.
