volt to ppm

[dwuihf]

Hi,

    i am using MQ-5 gas sensor to detect LPG and the output voltage is range 0-5v. this range is divided into sampling volts each = 0.00488

so the total samples=1023,  1 sample =5/1023 = 0.00488
 

i want to convert the amount of output voltage detected by gas sensor to PPM(part per million) . How?

Hi,

I am not sure if this is a Multisim issue. Are you trying to build a circuit for this gas sensor? If so, can you post the circuit so we can try to see what is going on.

sir,

how to convert voltage obtained from the CO sensor to the concentration of CO?

we need formula to calculate manually.................!
