Abstract

          In this work, a low-cost light sensor (400-700 nm) was developed for measuring blue light (400-500 nm) from portable electronic devices.  BH1750 sensor was selected for development, the sensor is a digital ambient light sensor that provided illuminance radiation between 1 to 65535 lx. The sensor was calibrated with standard radiometer as EKO spectroradiometer model MS-710 under cloudless sky conditions. The correction factor was obtained from relation between sensor data and blue light of standard radiometer. The results found that blue light from the sensor and the standard are in good agreement with root mean square different 0.53%. Then, the sensor was used for measuring blue light from portable electronic devices including two smartphones, two computers and two tablets. The amount of blue light emitted by smartphones, tablets and computers are in range 3.96-137.12 mW/m2, 3.00-90.95 mW/m2 and 26.58-218.35 mW/m2, respectively.
