Sensor module for use in low-cost weight measurement and sensing system

A sensor module comprising:

• a substrate configured to be mounted between a floor pan of a vehicle and a seat of the vehicle;
• a force sensing element disposed directly upon the substrate and configured to:
• sense a force applied thereupon;
• and
• generate a reading representative of the force applied thereupon in response thereto to provide a sensor reading,
• a wiring harness connected to the force sensing element and configured to transmit the sensor reading to a control module,
• wherein the substrate defines an aperture configured to surround a fastening element used to fasten the seat to the floor pan of the vehicle, the force sensing element defines an aperture aligned with the aperture defined by the substrate, and the substrate further comprises a collar circumscribing the apertures and configured to protrude through an aperture in a mounting foot of a seat, whereby crushing of the force sensing element is prevented when the sensor module is mounted between a floor pan of a vehicle and a seat of a vehicle,
• wherein further comprising a printed circuit board disposed upon the substrate and connected to the wiring harness,
• further comprising a cover strap disposed upon the printed circuit board, wherein the cover strap comprises a puck configured to be disposed between the force sensing element and the seat when the sensor module is mounted between the floor pan and the seat.
