Remote Temperature Monitoring System: Signal Conditioning by Bruno Feitosa Marques

This project outlines the implementation of a temperature sensor system split into modules, including signal conditioning components such as noise filter, amplifier, and signal limiter to ensure system functionality. Utilizing LM35 temperature sensor, 3 OPAs, inverters, and resistors. The simulation maintains voltage between 0V and 7V with an input of 0.39V.
