Abstract [en]

There has been an increasing focus on health in the every day life of people. Air

 

pollution has been an increasing problem for a long time, the world is contin-

ually trying to solve the problems regarding emissions from cars and industry.

 

While it is important to reduce outdoor air pollution, people often forget to

think about indoor air quality. As the average person spends up to 80% of their

time indoors, poor indoor air quality can have a much bigger impact on health

than outdoor air.

In this thesis a battery based indoor-air-quality-sensor-system is developed

and prototyped which can help people become more aware of the air quality

they are spending most of their time in. This system gives an overview of the

air quality throughout the day and can alert users to take measures to improve

the air quality around them.

The system is designed for the consumer market as an addition to Sikom’s

 

system or as a standalone product. Software with roots in the Nordic develop-

ment packages and hardware has been created to realize the system. The system

 

uses a nRF52840 chip from Nordic Semiconductor, which processes, stores and

sends data via Bluetooth.

This thesis is a continuation of two previous projects which has laid the basis

for this project. The result of this project is a working product which is almost

ready for mass production. The device can sample and quantify air quality and

sends the data to the users smartphone via Bluetooth.

 

This project has been created in cooperation with Sikom. Sikom is a Nor-

wegian company that provides products for monitoring and control systems for

 

homes and cabins.
