Android realtime sensor feed for the 1248 Geras IoT time series database.
NOTE: This project is experimental
Library module for realtime Geras publishing via MQTT using the Eclipse Paho client.
Client helpers for SenML and the Geras REST API using Gson, Retrofit and OkHttp.
Android app that feeds selected Sensor data to Geras via MQTT at a given series path. Supply your Geras API key as a resource value. A long running service will establish a wake lock and maintain SensorEventListeners and an MQTT broker connection for its duration.
// Create a Geras MQTT instance using your API key
GerasMqtt geras = new GerasMqtt("YOUR_GERAS_API_KEY");
// Add sensor monitors
// Note: sensors that return values in three dimensions will publish the root mean square
geras.addSensorMonitor("/foo/temperature", Sensor.TYPE_AMBIENT_TEMPERATURE, SensorManager.SENSOR_DELAY_NORMAL);
geras.addSensorMonitor("/foo/humidity", Sensor.TYPE_RELATIVE_HUMIDITY, SensorManager.SENSOR_DELAY_NORMAL);
geras.addSensorMonitor("/foo/light", Sensor.TYPE_LIGHT, SensorManager.SENSOR_DELAY_NORMAL);
// Set a location monitor
// Note: lat/lng coordinates will be published as discrete values
geras.setLocationMonitor("/foo/location", LocationManager.GPS_PROVIDER, 60, 10);
// Start the service to connect to the broker and start the sensor monitors
geras.startService(this);
// Publish an ad-hoc datapoint
// Useful for non-sensor information like microphone PCM data or battery level
geras.publishDatapoint(this, "/foo/battery", String.valueOf(getBatteryLevel()));
// Stop the service
geras.stopService(this);Copyright (C) 2014 readyState Software Ltd
