The QM95000Q digital sensor is the world’s most sensitive sensor, a 10x improvement over our previous generation digital sensors. Force is easily detected through thicker and stiffer materials. The digital output allows a direct connection to a host processor via an industry standard I²C interface.
The QM95000Q digital sensor is designed for “host-free” applications requiring autonomous sensing from power-up, without the need for any I2C commands to initialize the part. To achieve this, a dual function pin allows for a sensor trigger threshold to be set using an external resistor. In Always-On applications, this sensor offloads the host, allowing it to remain in a low-power state until woken up by an interrupt when a pre-defined sensor threshold is achieved.
The QM95000Q includes factory calibration for sensitivity, automatic sensor offset correction, and programmable temperature correction in conjunction with an on-board temperature sensor. It uses standard pick-and-place assembly and reflow soldering onto PCB/FPCB substrates. The QM95000Q comes with BSP, back side protection layer, for increased durability during assembly.
