After this week’s meeting, we received news about the sensor acquisitions that the sensor ZP07-MPSO3 was not going to be possible to acquire in time, so we changed this sensor to the sensor MQ2. This week, we finally have in our possession a sensor to measure the quality of air, MQ135, that measures C02. It was given to us by professor Teresa Vazão, whom we thank for this kindly gesture. We redid the sensor diagram that was on our website to make it easier to understand.
