Sencoch GZP6869D200KPP Digital Pressure Sensor, 0-200 kPa Range, I2C Interface, SOP-8 Package

The sensor communicates via a standard I2C interface. This allows direct connection to microcontrollers like Arduino, ESP32, or Raspberry Pi using just two wires (SCL and SDA) for reading digital pressure data, simplifying integration without analog-to-digital conversion.

No, the sensor requires a strict 3.3V DC supply as specified. Connecting it directly to a 5V logic level can damage the device. When using a 5V microcontroller, you must use a logic level converter for the I2C lines and a regulated 3.3V power source for the sensor's VDD pin.

This sensor measures gauge pressure, which is the pressure relative to the ambient atmospheric pressure. It reads zero when the measurement port is open to the atmosphere. Absolute pressure sensors, in contrast, measure relative to a perfect vacuum. This gauge sensor is suitable for applications like fluid level, flow, and differential pressure where atmospheric reference is needed.

The SOP-8 package is designed for surface-mount soldering onto a PCB. The pressure port is typically located on the underside of the package. A proper seal must be created using an O-ring or gasket between the sensor's port and your application's pressure chamber. Refer to the manufacturer's datasheet for recommended footprint and sealing guidelines.
