The system makes use of the already available hardware in the challenger kit, with some additional items.   Let me list out all the items necessary.   Raspberry Pi 4 MAX30102 sensor Pimoroni PIM487 Automation HAT PIM486 Enviro HAT PICO HAT Hacker PCB Insulated Copper wires for Anode and cathode linkage to the power supply Hot glue cylindrical pipe - a small piece Wire mesh Rubber tube O2 suction mask Buzzer RGB LED Power Bank DC power supply   The blood oxygen leve ...
Approaches:  Oxygen generator for a whole area (currently limited due to resource constraints) Portable oxygen generator for an individual (this project focuses on this) For approach 1, good quality atmospheric oxygen PPM sensors are costly and are out of our financial budget. One such module is AST SRZ-CA24-4 from OxyCheq.     For our demonstration, we use approach 2 where we use a MAX30102 Pulse Oximeter & Heart Rate Monitor sensor from Maxim Integrated.     C ...
Aim:  This project aims to tackle an emergency event of oxygen deficiency. In confined and restricted spaces, be it even a safe bunker/shelter during a global disaster, a workspace, or a rocket ship speeding to space and beyond, humans if present, will be needed to sustain the amount of oxygen for a prolonged period of time, within their body as well as the surrounding space. If personnel more than the allowed number are present in a confined space, oxygen can easily run out within that ...
