Pet project to capture, consume, store and analyse data from sensors.

The architecture consists of three key components:

1. sensor-device - Colocated sensors + IO board to capture raw data. Sensors can be colocated on a single device (monolith), or split out across multiple devices.
2. sensor-hub - Central hub used in the field to aggregate sensor data from multiple devices, process and route onwards to the backend.
3. backend - Scaled compute, storage and analytics system for the sensor data.

For this project, we are using a single monolithic sensor device with all sensors and an LCD attached to a one IO board. The following overviews the key implementation technologies used:

• sensor-device
  • Genuino 101 with Bluetooth LE
  • Sunfounder components:
    • Basic Temperature-humidity Sensor (DHT11)
    • Barometric Pressure/Temperature/Altitude Sensor (BMP180)
    • Digital Temperature Sensor (DS18B20)
    • I2C LCD (LCD1602)
• sensor-hub
  • Raspberry Pi 2
  • Bluetooth 4.0 LE USB micro adaptor
  • Python consumer service using bluepy
• backend
  • Server-side Akka/Spark cluster (TODO)
