Portable Device for Measuring Lighting Characteristics in Working Spaces

Knowing the characteristics of the lighting system in a working place is important as numerous studies have shown that the quality of light can influence the mood and productivity of people working in those spaces. This research proposes the creation of a portable device that can be used to measure characteristics of lighting systems in working places. The device is based on TCS34725 light sensors and is used to measure, in an automatic way, different light parameters. The paper presents an initial prototype of the device which includes a microcontroller board, light sensors, a step motor, a step motor drive and a Bluetooth (BT) module. Using the BT connection, the device can be controlled remotely using a smartphone, the data can be transmitted and recorded on the smartphone or can be sent to the cloud for storing and processing.
