Android Things Weather Station sample

This sample shows integration of multiple Android Things peripheral 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.

Schematics for Intel Edison Schematics for 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 public MQTT sandbox.

MQTT broker configuration

  1. In app/build.gradle, replace the buildConfigField MQTT_TOPIC value 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:// using e.g the mosquitto_sub command line tool

mosquitto_sub -h -t '[your_topic]'

Next steps

Now your weather sensor data is continuously being published to Google Cloud Pub/Sub:
