Abstract

As the value of assets in space increases, the need for protection from internal system faults and fires becomes necessary. The rapid nature of commercial space advancement contrasts the approach NASA utilized, and there is a paramount need for a Federal Aviation Administration (FAA) approved commercial off the shelf (COTS) solution to fire detection in space. Our objective is to develop a low size weight and power (SWaP) solution for an early fire detection system implemented as an industry standard. This work highlights the electrical systems which drive LED-based absorption spectroscopy earlyfire detection sensor which targets CO and CO2. The unit’s core logic is executed using a PIC24HJ series microcontroller with custom libraries that interface with several devices through analog, I2C, and SPI communication protocols. The prototype unit is slated for an upcoming sub-orbital flight test which will record and log measurements data onto a microSD card for subsequent post-flight analysis.
