Getting zero value

When I’m trying to connect LM35 and Max30100 to blynk app with nodemcu. I was getting zero value for pulse oxymeter. When i removed the LM35 section then the pulse oxymeter takes correct reading . What might be the issue . hope anyone would suggest the solution

Please have a look at the code attached below …

Just a guess, but is the analogRead for the LM35 hitting the I2C lines that the Max30100 is using?

LM35 taking analog read through A0 . max30100 i2c lines are D1 and D2.

Too bad someone with four posts doesn't know how to post properly so I cannot see the code. :(
