Sencoch GZP6899D001KPW Pressure Sensor, 3.3V, 100nA, I2C, Range: -1 kPa to 1 kPa, SOP-8 Package

The sensor requires a 3.3V DC power 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 sensor longevity.

The sensor uses a standard I2C (Inter-Integrated Circuit) serial communication protocol. Connect the SDA (data) and SCL (clock) lines to your microcontroller's corresponding I2C pins, along with 3.3V and GND. You will need to use the specific I2C address and register map provided in the Sencoch datasheet to read pressure data.

This is a gauge pressure range, meaning it measures pressure relative to ambient atmospheric pressure. A reading of -1 kPa indicates a vacuum (pressure below atmosphere), 0 kPa equals ambient pressure, and +1 kPa indicates pressure above atmosphere. It is designed for measuring small differential pressures, such as airflow or slight pressure differences.

No, the GZP6899D001KPW is a gas pressure sensor with a MEMS piezoresistive diaphragm exposed via a port. It is not sealed for direct liquid contact or immersion. Using it with liquids may cause damage, corrosion, or inaccurate readings. For liquid pressure, a sensor with a sealed, media-compatible isolation diaphragm is required.

The 100nA standby current dramatically extends battery life in always-on or frequently sampling applications. This feature is critical for portable medical devices, wireless sensor nodes, and smart wearables where power consumption is a primary design constraint, allowing for months or years of operation on a single small battery.
