A good PCB layout for the MPX2100AP involves placing the sensor near the edge of the board, using a ground plane to reduce noise, and keeping the analog and digital traces separate.
Calibration involves applying a known pressure to the sensor and adjusting the output voltage to match the expected value. A calibration procedure can be found in the application note AN1666.
The maximum pressure rating for the MPX2100AP is 100 psi (690 kPa), but it's recommended to operate within the specified range of 0-50 psi (0-345 kPa) for optimal accuracy and reliability.
The MPX2100AP is not designed for use in humid or wet environments. It's recommended to use a protective coating or enclosure to prevent moisture ingress and ensure reliable operation.
Temperature compensation can be achieved using an external thermistor or thermocouple to measure the temperature, and then applying a correction factor to the output voltage based on the temperature coefficient specified in the datasheet.
