arduino - How to calculate Gas sensor PPM from analog ...

In order to calculate current PPM you need to find sensor resistance RS first. Normally it is done by simple formula for voltage divider: RS/RL = (V-Vs)/Vs, where RL is load resistor. When measured in clean air the calculated RS becomes R0. The first code uses this equation, however I have no idea why they divide this by some constant. IMHO the formula for ratio should be simple RS/R0 = RS_gas ...

Force Sensing Resistor (FSR) Arduino Tutorial (3 Examples)

03/02/2019· Calculation example. The output voltage (Vout) that we measure with the Arduino is described by the following equation: Vout = Vcc x R / (R + Rfsr) So the voltage is inversely proportional to the FSR resistance. Note that the output voltage you measure is the voltage drop across the pull-down resistor, not across the FSR. When no force is applied, the FSR resistance will be really high, take ...
