Problem Definition

The open space is an important part for every working environment. It can boost employees' efficiency and make work less stressful and depressive. Moreover, there are several sustainability aspects that could be satisfied by implementing control features. The open space at LUT is not restful enough. It just has basic facilities such as coffee machine, arm chairs, a guitar and TV.

Goals

The goals of the project is:

Create pleasant virtual environment with affecting human’s senses;

User-friendly design with enhanced control;

Satisfy workers’ needs;

The artificial environment should be close to the natural conditions.This can be achieved by implementing sounding (relaxing music), humidifying the air with different smells (forest, blossom flowers, etc.), smart lighting (with predefined lights for corresponding natural scenes). In the same time, control should be seamlessly embedded into open space and be user-friendly.

System Architecture

Automation server: FHEM (Freundliche Hausautomatisierung und Energie-Messung)

FHEM is a server for home automation tasks. The server utilizes different front-ends and Web interfaces. It is intended to automate common tasks in a household, such as controlling heating, lights, logging events (temperature, humidity, security). FHEM works with a vast number of home automation technologies and protocols: FS20, HomeMatic, KNX, ZWave, EnOcean, X10, etc.

HW platform: Digital Human Services (DHS) Computertechnik

Single-board computer with the touch screen and RF interface.

Communication protocol (Devices-Server): FS20

Non-encrypted technology that operates at sub-1 GHz band and utilizes amplitude modulation.

Sensors and Actuators:

Sensors:

Occupancy sensor (emulated by remote control)

Thermostat (FHT80B-3)

Thermosensor (HMS100 TF) - used for Smart-Coffee machine

Actuators:

Smart Plug (Switch) - used for Sounding and Humidifying

Philips Hue (bridge and one light bulb) - used for creating light scenes

Overview of protocols for home automation

Bluetooth Low Energy Bluetooth low energy (BLE) was specially designed for the Internet of Things (IoT). It implements low energy functionality which makes it perfect for devices that utilize energy harvesting or batteries. Major operating systems and hardware architectures support BLE which enables its deployment for a broad range of devices, from home appliances to smart wearables and sensors. Insteon
