Humans are sensitive to both daylight as well as the intensity of lamps. The purpose with this project is to measure the light intensity with a body-area-network when moving and to couple the value to user perceived need and comfort.

The students will implement a system which can be used to measure light intensity received by individuals both indoor and outdoor. Each user will carry a wearable sensor (a watch or a brooch) to measure light exposure when moving. The light intensity readings from wearable sensors will be compared with the readings from stationary sensors to optimize the energy consumption for electricity, such as appropriate intensity of lamps. All sensing data should be transferred to a server through a smart phone. The aim of the project is to present amount of light that each person received individually at different locations. Students in this project should be voluntary to carry the wearable sensors and smart phones for this study.

Team size 3 - 4 persons. For a larger team the project should be complemented with a scientific report on how much light users are exposed to daily and how they perceive comfort in a building.

6 wearable light intensity sensors, 6 smart phones, 4 stationary light intensity sensors, and 1 laptop.
