This sample integrates multiple Android Things peripheral drivers together to build a connected Weather Station.
If you have the Raspberry Pi Rainbow Hat for Android Things, just plug it onto your Raspberry Pi 3.
On Android Studio, click on the "Run" button. If you prefer to run on the command line, type
bash ./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. - If a Google Cloud Platform project is configured (see instruction below), it will publish the sensor data to Google Cloud PubSub.
app/src/main/res/raw/with the contents of the credentials you downloaded in the previous steps.
app/build.gradle, replace the
buildConfigFieldvalues with values from your project setup.
After running the sample, you can check that your data is ingested in Google Cloud Pub/Sub by running the following command:
gcloud --project beta pubsub subscriptions pull
Note: If there is no
app/src/main/res/raw, the app will run offline and will not send sensor data to the Google Cloud Pub/Sub.
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
This sample app is currently configured to launch only when deployed from your development machine. To enable the main activity to launch automatically on boot, add the following
