A field replaceable desiccant cartridge and device, method and system there for is provided. The cartridge comprises: a housing comprising an insertion end configured to removabley mate with an aperture of a device, the insertion end configured to generally prevent moisture from entering the device when mated; a desiccant located in the housing; a circuit located within the housing, the circuit in contact with the desiccant, the circuit configured to change resistance as the desiccant changes in moisture content; one or more electrodes located at an exterior of the insertion end, the one or more electrodes in contact with the circuit; and, one or more holes through the insertion end, configured to expose the desiccant to an exterior of the housing so that the desiccant can absorb moisture there from. Devices configured with the cartridge can report moisture levels to a server, which can track problems associated with moisture in the devices.
