[EN] We report herein the construction of an electronic device to perform the real-time
digitalization of the color state of the optical chemosensors used in the detection of dangerous
gases. To construct the device, we used open-source modular electronics, such as Arduino and
Sparkfun components, as well as free and open-source software (FOSS). The basic principle
of the operation of this device is the continuous color measurement of a chemosensor-doped
sensing film, whose color changes in the presence of a specific gas. The chemosensor-sensing
film can be prepared by using any of the widely available chemosensors for the desired gas.
Color measurement is taken by two TCS230 color sensor ICs, reported to the microcontroller,
and the results are displayed on an LCD display and pushed through a USB serial port. By
using a cyanide optical chemosensor, we demonstrated the operation of the device as a HCN
gas detector at low concentrations.
