LM35 in combination with other sensors

Hi community,
I am working on a problem quite a long time, but unfortunately I can’t fix it.

My sensor LM35 works without other sensors in my circuit good, but if I add a humiditysensor and a photosensor the temperature values swing crazy (for example: once 16 degrees, then 22, next 16 or 23). The other sensors work in combination with LM35 good - but LM35 not. But WHY? :frowning:

You read two analog signals. Internal capacitance makes the two interfere.

read each analog twice. eg:

analogRead(1); tempval=analogRead(1);
