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 ...

Carbon Monoxide Gas Sensor MQ-7 - Arduino Project Hub

02/04/2020· I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.

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 ...

Water Flow Sensor: Pinout & Interfacing with Arduino ...

The maximum portion of the Arduino code is self-explanatory except for the calculation part of the water flow rate in this line: Liter_per_hour = (Pulse_Count * 60 / ) As you know that the pulse_count variable contains the number of pulses in one second which is generated by the output pin of the water flow sensor. We multiply the Pulse_Count value with 60 to convert this measurement into ...
