Sencoch GZP6897D001KPW Pressure Sensor, 3.3V, I2C Output, Ultra-Low Power (100 nA), -1 kPa~+1 kPa, SOP-8

The sensor features an ultra-low standby current of just 100 nanoamperes (nA). This exceptionally low power draw makes it perfectly suited for battery-powered and energy-harvesting applications where minimizing overall system power consumption is critical for extended operational life.

This sensor communicates via a standard I2C digital interface. It is directly compatible with most modern microcontrollers that support I2C communication, including Arduino boards (using the Wire library), ESP32, ESP8266, Raspberry Pi Pico, and STM32 development platforms, requiring only two signal wires (SCL and SDA) for data transfer.

The GZP6897D001KPW is configured as a gauge pressure sensor. This means it measures pressure relative to the ambient atmospheric pressure. Its specified range of -1 kPa to +1 kPa indicates it can measure both slight vacuums (negative gauge pressure) and slight overpressures (positive gauge pressure) relative to the local environment.

The sensor requires a stable 3.3-volt DC power supply. It is not rated for 5V logic or power inputs. For systems operating at 5V, a level shifter must be used on the I2C communication lines to avoid damaging the sensor's internal circuitry.
