In a point of our research we’d tested too many sensors and all had pros cons. In order to make a better decision, we decided to score our sensors. In our analyses we are considering three aspects : aesthetics, integrability and sensibility.
The results you find bellow, as well as the circuit that we used .
Until this point we were trying to figure out which value of resistances were the best to deliver a bigger range of values in the serial monitor, therefore we took notes. With further research we’ve discovered that if one measure in the multimeter the highest and lowest voltage, add those values and dived by two, one will be able to have the average voltage and use this average voltage value as a resistor.
