Micro:Bit Weather Station

Build a weather station using the Micro:Bit and a couple of ☒CHIPs from XinaBox, the ☒SW01 Weather Sensor, and the ☒IM01 Micro:Bit Interface. You can easily modify the code to add other data from the Weather Sensor, such as Barometric Pressure, Altitude and Humidity.

Follow this 2 min video to see the complete project:

Step 1: Assemble the circuit

• Click the IM01 and the SW01 together using a ☒BUS connector (from the XC10 pack). Make sure that the ☒CHIPs faces the same way up, so you can see the the SW01 name and the IM01 name both facing up. Make sure the connection is aligned, there is only 2 sides of the SW01 that fits the IM01, but you can use any of the IM01 connections.

• Click the Micro:Bit into the IM01. Make sure the LEDs faces up - same way as the SW01 name and the IM01 name.

• Attach a Micro-USB connection from your computer to the Micro:Bit. Notice the yellow LED on the bottom side turning on.

Step 2: Install package

• Open a browser and go to https://makecode.microbit.org

• Scroll down to "Advanced"

• Then Scroll down to "Add Package"

• Search for "weather" and click on "weather-bit"

Step 3: Programming

• Drag and drop code elements until you get something that looks like the image below.

• You can also cheat and click on the "{ } JavaScript" button on the top and simply copy and paste the code in the code section below. Click on "Blocks" again to see the result.

Step 4: Flash and Test

• Click on "Download"

• Drag the downloaded file, typically named: microbit-Untitled.hex, to your Micro:Bit drive, typically name: MICROBIT.

• See the result on the scrolling LED display.

• Place a finger on the sensor to see the temperature go up ... hopefully!
