This document provides a step by step guide to set up the HAL, retrieve data from the sensor devices, send it to various other devices / IoT Core Team.

Features

  • Support for numerous sensors.

  • Modular and extensible structure.

  • Simple UI to enable user to configure his devices and sensors.

  • Secure data transmission to other devices/IoT Core Layer.

  • Intermediate data storage.

  • Detection of sensor failures.

  • Machine to Machine communication.

Deployment

  • Clone this repo

  • Assuming that the config web server(https://gitlab.lrz.de/IoT-Practicum-Group/sensors/tree/v2018) is running smoothly, use it to register yourself, create your device and edit the device details accordingly.

  • Make sure to mention the appropriate sensor, communication and security protocols without fail.

  • Make sure that the device is connected to Internet.

  • Install python3.5+ on the device

  • Run sudo bash install.sh <config-web-server-ip:4000>

Components Supported

  • Raspberry Pi:

  • List of sensors mentioned in the SensorKit X40

  • Odroid XU4:

  • Weather Board

  • myAHRS+

  • List of sensors mentioned in the SensorKit X40 that are based on RPGPIO library

Usage

To send data to IoT Core Team

  • Register the device and respective sensors with the IoT Core Team via http://iot.pcxd.me:8080/

  • Note down the Sensor_ID, Device_ID and also download the Device Key.

  • Login to the config web server and modify the config details accordingly

  • HAL_custom_id = Sensor_ID

  • Topic = Device_ID

  • Bootstrap Server Username = "JWT"

  • Bootstrap Server Password = Device Key

  • Run sudo bash install.sh <config-web-server-ip:4000>  to collect data from the sensor and send it to the IoT Core Team.

Machine-to-Machine Communication

To send data to another machine:

Follow "To send data to IoT Core Team" section except,

  • Topic = (Could be anything)

  • Bootstrap Server Username = (mosquitto username of listener machine, if any or a blank space)

  • Bootstrap Server Password = (mosquitto password of listener machine, if any or a blank space)

To receive data in another machine

  • Download files from m2m folder

  • Run sudo mosquitto_install.sh

  • To receive data, run - sudo python3 mqtt_subscribe.py
