A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital signals separate, and use a common mode filter to reduce noise.
Calibrate the device using a thermocouple or a precision temperature source. Ensure good thermal contact between the device and the heat source, and use a low-noise, low-impedance connection to the microcontroller.
The maximum cable length is approximately 10 meters. Use a shielded twisted pair cable, and terminate the lines with a 100-ohm resistor to minimize reflections and ensure signal integrity.
Yes, the device can be used in high-vibration environments. Ensure the device is properly secured to the PCB, and use a vibration-resistant connector and cable. Apply a conformal coating to protect the device from moisture and contaminants.
Check the power supply voltage, clock frequency, and data transmission rate. Verify the digital output is properly connected to the microcontroller, and use a logic analyzer or oscilloscope to debug the signal.
