1. A CO2 sequestration sensor system, comprising:
an underground sub-assembly comprising one or more sensors configured to detect at least one attribute associated with CO2 sequestration below a terranean surface, the one or more sensors comprising a frequency sensitivity of between 0.01 Hz and 300 Hz, the underground sub-assembly comprising:
a conduit having at least one open end configured for insertion from the terranean surface into a subterranean zone to a particular depth, the conduit comprising a volume that is humanly accessible from the terranean surface through the at least one open end and sized to at least partially enclose the one or more sensors, and
a cap or seal configured to fit over the at least one open end to enclose the one or more sensors within the volume; and
an above-ground sub-assembly positionable on the terranean surface proximate the underground sub-assembly and comprising at least one controller communicably coupled to the one or more sensors and a housing that at least partially encloses the controller and is less than a cubic foot in volume.
