A progressing cavity rotor facilitates pumping applications in progressing cavity pumping systems by ensuring a desired shape of the rotor. Therefore, the heat dissipation package structure is fabricated through simplified fabrication steps at low cost, and also the problem that the chip is easily damaged in a package molding process of the prior art is overcome. The micro-controller receives data from the sensor and compass and is programmed to autonomously detect magnetic signals having particular characteristics of interest.
