CubeSat Temperature Monitoring System using LM35 Sensor

Temperature monitoring is one of the essential subsystems in embedded electronics, aerospace systems, satellites, and CubeSat missions. Electronic components operating in space and embedded environments are highly sensitive to thermal variations. Therefore, a reliable and compact temperature sensing system becomes an important part of the spacecraft health monitoring process.This project presents the design and implementation of a PCB-based temperature monitoring system using the LM35 analog temperature sensor. The complete schematic design, PCB layout generation, routing, footprint assignment, electrical verification, and 3D visualization were successfully developed using KiCad.The system includes an LM35 temperature sensor, LED indication circuit, current limiting resistor, and output connector header for interfacing with external embedded systems such as Arduino, ESP32, STM32, or CubeSat onboard computers.The project demonstrates practical skills in PCB design workflow, schematic development, hardware layout planning, track routing, and embedded hardware preparation relevant to aerospace electronics and embedded system engineering.
