Abstract:
A digitally accessible sensor (DAS) assembly includes a sensor, such as a gas sensor, attached to a printed circuit board which includes an analog-to-digital converter, and a digital interface. This modular design significantly shortens the analog signal path from the sensor and provides digital information to the instrument microcontroller, and thereby reduces noise levels from the sensor and circuitry. The circuit board design also includes a non-volatile memory unit allowing retention of information related to the sensor and its operation and/or the application, and may include an amplifier for amplifying the low level analog signal.
