Octopus BME280 Pressure Sensor is an electric brick, which has integrated temperature sensor, air pressure sensor and humidity sensor onboard. We can use it to measure humidity, temperature and air pressure, or even to calculate the altitude according to the measured air pressure.
Features
Low power consumption and small size.
3mm standard positioning hole.
Rated 3.3v power supply, which is enough to support micro:bit.
Support I2C and SPI protocol.
Quick Start
Hardware Connection
Connect the sensor to I2C connector on octopus:bit using a jumper cable.
Insert micro:bit into the edge slot of octopus:bit.

Programming
Click to open Makecode, write your code to read air pressure values and display it on the micro:bit screen.
Result
Air pressure values are scrolling on the micro:bit screen with unit mb.

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
