Hello Community,

I configured  my hardware using LMP91000 and LMP7721 as shown in thread,


Also, I used equation to find gas sensor concentration using,

But, after reading data from analog pins I can't get output as expected both WE and AE pin gives nearly same output sometimes it shows negative ppm.

Could anyone tell me that which config I did wrong?

Thanks in advance,
