Abstract
A system for gathering downhole measurements includes a drill bit, at least one nozzle receptacle located on the drill bit, and a sensor system. The sensor system has a sensor housing, a flow path extending through the sensor housing, wherein the flow path allows fluid to flow through the sensor housing, and an internal cavity provided within the sensor housing separate from the flow path. The internal cavity contains components that include at least one sensor for gathering data about drill bit conditions and downhole conditions, a powering unit, a printed circuit board, and an electrical conductor, wherein the sensor housing is installed in the at least one nozzle receptacle.
