Sencoch GZP6857D040KPP Digital Pressure Sensor, I2C, 3.3V, Ultra-Low Power, Range: 0-40 kPa

The Sencoch GZP6857D040KPP is designed for a single 3.3V DC supply. Exceeding this voltage may damage the internal MEMS and signal conditioning circuitry. Ensure your power source is regulated to 3.3V ±5% for optimal performance and sensor longevity.

This sensor uses a standard I2C communication protocol. Connect the VCC pin to 3.3V, GND to ground, SDA to the I2C data line, and SCL to the I2C clock line on your microcontroller (e.g., Arduino Uno, Raspberry Pi, ESP32). You will need to use a library or write code to read the pressure data from the sensor's I2C register map.

The 100 nanoampere (nA) standby current indicates the extremely low power the sensor draws when in a sleep or idle mode between measurements. This feature is critical for battery-powered applications, significantly extending operational life by minimizing background power consumption.

The GZP6857D040KPP is a gauge pressure sensor with a port designed for dry, non-corrosive gases like air. It is not inherently sealed against liquids. For liquid pressure applications, you must ensure the media is compatible with the sensor's internal diaphragm material and use appropriate isolation methods to prevent damage.
