Sencoch GZP6897D2.5KPW Pressure Sensor, 3.3V I²C Output, -2.5 kPa~+2.5 kPa Range, SOP-8 Package

The sensor is designed for a single 3.3V DC supply. Exceeding this voltage may damage the internal MEMS and signal conditioning circuitry. Ensure your system's power rail is regulated to 3.3V ±5% for optimal performance and accuracy.

The sensor uses a standard I²C (Inter-Integrated Circuit) interface. Connect the SDA and SCL pins to your microcontroller (e.g., Arduino, ESP32) with appropriate pull-up resistors (typically 4.7kΩ). The default I²C address is specified in the datasheet, and communication follows standard read/write protocols for reading pressure data registers.

A range of -2.5 kPa to +2.5 kPa indicates it measures gauge pressure relative to atmospheric pressure. Negative values represent vacuum or pressure below ambient, while positive values indicate pressure above ambient. This symmetrical range is ideal for applications measuring small pressure differentials, such as in respiratory devices or airflow monitoring.

Yes, its ultra-low 100 nA standby current makes it exceptionally suitable for battery-powered and always-on IoT applications. You can put the sensor into a deep sleep mode between measurements to significantly extend battery life in portable medical monitors or environmental sensing nodes.

The GZP6897D2.5KPW is a gauge pressure sensor with a port designed for air or non-corrosive gas media. It is not inherently sealed for direct liquid contact. For liquid pressure applications, a protective isolation diaphragm or a sensor specifically rated for liquid media is required to prevent damage or contamination.
