Development of Wearable Tool for Measuring Melanopic Equivalent Daylight Illuminance at the Eye Position
Light is a crucial environmental factor that synchronizes human circadian rhythms,affecting health through non-visual pathways,such as the regulation of biological processes. However,current methods for measuring and evaluating light environments fail to adequately account for the non-visual biological effects of light. Moreover,they lack practical tools for comprehensively measuring human light exposure. This study addresses the need for health-oriented lighting by designing and implementing a wearable device for measuring melanopic Equivalent Daylight ( D65 ) Illuminance ( melanopic EDI) . This tool integrates knowledge from biology,photometry,and electronics to provide a comprehensive assessment of environmental light quality and support the creation of health-promoting lighting environments based on scientific data. The research begins with an overview of existing measurement instruments,outlining functional requirements and design considerations for different user groups and measurement scenarios. The ESP32 microcontroller,AS7343 sensor,and Arduino IDE were selected for hardware and software development. A data collection,transmission,storage,and processing program was developed,and the device's housing was designed using 3D printing technology. Validation tests showed that the device's measurements were within 5％ of those from a Konica Minolta spectroradiometer. Additionally,the device offers a comfortable wearing experience and can continuously measure at a frequency of 1 Hz for up to 12 h.
