You can connect the sensor to the left or right side of the board. (Where it can be connected varies depending on the connector type.)
When connecting a sensor, the (+) and (-) poles of the power supply cross each other in an X shape. Please be careful.
BMP280 is a sensor that can quickly and precisely measure the temperature and atmospheric pressure.
However, the measurement range of atmospheric pressure is 300 to 1100 hPa, so there is a risk of errors occurring when measuring higher than atmospheric pressure.
BMP280 does not have a humidity measurement function. To measure humidity, please use BME280.
- You have to connect a 5V USB power source. (3V battery cannot be used)
- Micro:bit only works with v2.00 or later products.
- Please use the Chrome browser if possible. It may not work in the in-app browser of social media (e.g. Facebook).
- It works on a PC or Android device that supports Bluetooth. Operation on Apple devices is not guaranteed.
- This app consumes a lot of CPU resources. Make sure your smart device’s CPU performance is good enough.
- Firmware installation is required on the micro:bit for first use. Click the ‘Firmware Download’ link to install it on your micro:bit. You don’t need to access ‘makecode.microbit.org’ since you just need to save the file to the microbit folder.
- If the connection to the micro:bit is successful, ‘B'(BMP280) will be displayed on the micro:bit’s LED.
- If the connection doesn’t work, turn the micro:bit completely off and back on, or click the reset button on the back.
