1. A method for sensing downhole measurement parameters in a well, comprising the steps of:

  • providing a plurality of sensor modules, each having a sensor section, a storage register and a power source which are encapsulated in a protective outer covering, and operative for sensing at least one desired parameter and storing a value therefor in a storage register;

    injecting the plurality of the sensors modules into a flow line connected to the drill string;

    pumping the sensor modules downhole, through a lower portion of the drill string and into an annulus defined between the drill string and a borehole of the well, detecting the desired parameter and storing the value therefor in the storage register; and

    passing the sensor modules to a read unit to read the value of the parameter stored in the storage register.
