I am doing a hybrid-car project for my school. On the vehicle, I installed many sensors (RPM, temperature, current, voltage). Originally those sensors would be read only by one microcontroller. Now I want to install a data logging device for recording data off the same set of sensors. The problem is if the microcontroller and data logging device read the same signal, there would be loading effect..(different input impedances form a voltage divider) I really don't want to buy an extra set of the same sensors just for my data logger.
Is there a way to solve this?
