“…Para confecção da CSSC foi utilizada metodologia previamente descrita na literatura. 8 A síntese da meso-porfirina base livre (Figura 2) foi feita de acordo com o procedimento descrito por Ribeiro et al 9 A calibração da CSSC foi feita através de um fotoradiômetro digital e portátil, modelo HD2302.0 (Delta OHM, Pádua, Itália). Montou-se um aparato simples, que possui uma lâmpada LED de 60 W, de altura regulável, para gerar uma variação de intensidade luminosa sobre a superfície que continha a célula solar.…”

The present article illustrates the creation of a Smartwatch from the cardanol, the major constituent of the cashew nut shell liquid. In this proposal, cardanol was used in the synthesis of a photoactive pigment for the application in a dye-sensitized solar cell, inserted in the display of the device. The clock was made with the objective of measuring the ambient light radiation, through an electric signal corresponding to the incidence of light, using Arduino Nano 3.0 card for data storage, analysis and transmission via bluetooth. In addition, a phenolic resin was prepared from the cardanol to produce the watch carcass. A comparison between the cell assembled in this work and a silicon solar cell showed low relative errors regarding the captured electrical signal (ranging from 3.80-8.28 %) when compared to a solarimeter, proving that the mounted photovoltaic device can be used efficiently to measure solar radiation. The production of this Smartwatch showed advantages due to its portability, use of renewable raw material, and to serve as a pedagogical tool in an environmental education context.
