ABSTRACT

The development of many applications and the incorporation of different sensors in smartphones potentiate their use in different contexts, including the Occupational Safety & Health domain. Like any other measurement device, mobile phones must comply with accuracy and precision requirements. Therefore, a set of nine smartphones and 14 applications were tested against a lux meter, over four illuminance levels (300 lx, 500 lx, 750 lx and 1000 lx) and three correlated color temperatures (2700 K, 4000 K and 6500 K). Statistical significant differences were registered between the values displayed by the mobile phones and those of the lux meter, suggesting that smartphones are not suitable for measuring illuminance and decide on the adequacy of lighting in occupational settings.
