Android Things Weather Station sample
This sample shows integration of multiple Android Things peripheral to build a connected Weather Station.
- Android Things compatible board
- Android Studio 2.2+
- Rainbow Hat for Android Things or the following individual components:
If you have the Raspberry Pi Rainbow Hat for Android Things, just plug it onto your Raspberry Pi 3.
Build and install
On Android Studio, click on the "Run" button. If you prefer to run on the command line, type
./gradlew installDebug adb shell am start com.example.androidthings.weatherstation/.WeatherStationActivity
If you have everything set up correctly:
- The segment display will show the current temperature.
- If the button is pressed, the display will show the current pressure.
- If a Piezo Buzzer is connected, it will plays a funny sound on startup.
- If a APA102 RGB Led strip is connected, it will display a rainbow of 7 pixels indicating the current pressure.
- Sensor data will be published to the iot.eclipse.org public MQTT sandbox.
MQTT broker configuration
app/build.gradle, replace the
MQTT_TOPICvalue with the topic you would like to use to publish sensor data to your MQTT broker.
After running the sample, you can check that your data is published to the Eclipse IoT broker at tcp://iot.eclipse.org:1883 using e.g the mosquitto_sub command line tool
mosquitto_sub -h iot.eclipse.org -t '[your_topic]'
Now your weather sensor data is continuously being published to Google Cloud Pub/Sub:
- process weather data with Google Cloud Dataflow or Google Cloud Functions
- persist weather data in Google Cloud Bigtable or BigQuery
- create some weather visualization with Google Cloud Datalab
- build weather prediction model with Google Cloud Machine Learning
