This is the first sub-project in the life support system. It is a canister to hold at least 500cc of of Sodasorb HP 6-12 and an air handler to maintain air flow through the medium. Sensors and a control system should measure the inlet and outlet O2 and CO2 levels. Much of this technology may be borrowed from the Plant Respiration Test Apparatus (isr-003). A small uC is used to translate TTL level RS232 to send sensor data to the bus. A small tank should be installed in the bottom near the outlet to catch condensation.
