i'm working with a alphasense CO-AF sensor & i need to find out the CO quantity in ppm . i referred to the data sheet of the device and i dont know how to convert the given sensitivity specification to ppm.here is the link to the DATASHEET.can anyone help me out.
The sensitivity in the data sheet says that, for 1 PPM change in the gas concentration, there will be approximately 55 to 90 nA of current change. It is always relative and hence, initial calibration is very important. We are using several other gas sensors from the same vendor.
