Integration Tips for Arduino, Raspberry Pi, and Microcontrollers 🤖

• Power the sensor from a regulated 5 V rail commonly available on Arduino and many electronics modules.
• If your model provides an analog voltage output, connect it to an ADC input on a microcontroller (e.g., Arduino). For Raspberry Pi, use an external ADC HAT/module to acquire the signal.
• Use a common ground between the sensor and your controller; keep leads short or use shielded cable to minimize noise in data acquisition.
• Implement software calibration and temperature compensation for best accuracy across the specified compensation temperature range.
• Ensure the measured medium is non‑corrosive to stainless steel and ceramics. Apply thread sealant compatible with 1/8" NPT fittings.
• Observe IP65 and Ex ia II CT6 requirements during installation and operation.

This compact, robust sensor is a dependable choice for embedded systems, industrial automation, IoT projects, and electronics components testing where precise pressure monitoring is required.
