Smart Sensors: Microprocessor Based Self-Calibration |
|
|
|
J. Gordon Electronic Design provided electronic design and software development for a self-calibrating sensor for a major sensor manufacturer. Potentiometer adjustments for sensitivity were replaced with a one-button intelligent "learn" mode.
The smart sensor is designed to be self-calibrating in a simple one-button learn mode. Calibration feedback is via LED bar graph used to show signal strength in normal operating mode.
The PIC16Cxx processor family was used for the "brains" of the smart sensor. The processor includes an internal A/D converter plus digital I/O.
Optical event and proximity sensors are becoming smarter, thanks to microprocessor technology. Sensitivity adjustments once requiring a potentiometer adjustment now require only the push of a button for automatic calibration of the smart sensor.
J. Gordon Electronic Design provided electronic design and software development for the first self-calibrating sensor in the product line of a major sensor manufacturer. The Microchip Technologies PIC16Cxx family processor was chosen for its high performance at low cost, and its ready availability.
Cost-performance ratios as well as product availability are always top concerns. At J. Gordon Electronic Design, we invest substantial time and effort in staying informed of new technologies. We want to stay on top of what's hot in the embedded microprocessor market. |
