This week, the team made a lot of headway in chemical reaction running. By changing concentrations of different reactants, a much faster reaction time was obtained. Moreover, new chemical reactions compatible with our colorimetric sensor were identified and are going to be tested in the following days. Also, a lot of successful testing was done with the tube fittings and the motor-impeller assembly. As a highlight of our week, the team managed to create a final circuit design with all the sensors, pumps and motors and the results looked quite promising.
