I have a circular chart recorder which has a 0 - 1 voltage input for FSD on the chart. I want to display temps, and use an LM35 temp sensor so that minus 5 deg C corresponds to 0V, and 35 deg C corresponds to 1V. This is my annual range near London.
I have stabilized +5 and 0V available, and can add a ICL7660 to generate -5V, to read below zero.
Any circuit ideas please?
Thanks
