Sencoch GZP6891D005KPW SOIC-16 Differential Pressure Sensor, −5 kPa ~ 5 kPa, I²C Digital Output, 3 V ~ 5.5 V

The sensor operates from a single supply voltage of 3.0V to 5.5V DC. This range makes it directly compatible with both 3.3V logic systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a level shifter.

The sensor provides a standard I2C digital interface. You will need to connect the SDA (data) and SCL (clock) lines to your microcontroller, along with power (VDD) and ground (GND). Refer to the datasheet for the specific I2C device address and register map to read the calibrated pressure data.

Yes, the specified range of -5 kPa to +5 kPa indicates it is a true bidirectional differential pressure sensor. It can measure both positive and negative pressure differentials relative to the reference port, making it suitable for applications like flow direction detection or suction monitoring.

The Sencoch GZP6891D005KPW has a typical accuracy of ±2% of the full-scale range (±5 kPa). This accuracy includes the effects of non-linearity, hysteresis, and repeatability across the compensated temperature range as defined in the official datasheet.

Yes, its application notes list medical and healthcare uses. Its MEMS piezoresistive technology and digital I2C output provide the precision and reliability needed for non-critical medical monitoring, such as in respiratory equipment or diagnostic devices. Always verify it meets the specific regulatory standards for your end application.
