lm35 pic
In figure below is the schematic of a smart sensor module. I want to know why do we need to connect the lm35(temperature sensor) to a operational amplifier to pic MCU? What is its operation? I also want to know the operation of the circuit of a mpx5100( pressure sensor) connected to the pic MCU.
