Abstract:
1. A downhole sensor system, comprising: a plurality of downhole sensors disposed on or within a downhole component of a tool string and, at least one of the plurality of sensors adapted to detect a characteristic of a downhole formation adjacent the downhole component, the plurality of downhole sensors having a variable first sampling rate controlled by a processing element, and the processing element being in electrical communication with at least one of a tool string rate-of-penetration sensor and a tool string rotational speed sensor; a switchbox configured to connect at least two of the plurality of downhole sensors in series and in parallel; wherein the processing element is adapted to cause the switchbox to change a connection status of the at least two downhole sensors from one of parallel to series and series to parallel in response to at least one of the rate-of-penetration and the rotational speed of the tool string.
