Hi,
I am building a circuit to measure temperature difference within 2 lm35dz by using pic16f877a.
I have a problem on lm35dz on the accuracy of adc of pic16f877a. It is realised that the accuracy of of lm35dz is 0.25 'C. After it is connected to adc of pic16f877a with 10 bits, the accuracy become 0.50 'C. So how can I do in order to achieve back the 0.25 'C of accuracy?
Thank you.
