Sencoch GZP6859D005KPP MEMS Pressure Sensor, 0-5 kPa Range, 3.3V I2C Output, SOP-6 Package

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

Connect the sensor's VDD to 3.3V, GND to ground, SDA to your microcontroller's I2C data line, and SCL to the I2C clock line. Pull-up resistors (typically 4.7kΩ) are required on both SDA and SCL lines. You can then use standard I2C library functions (e.g., Wire.h for Arduino) to read the device's register map, which contains the calibrated pressure data.

A gauge pressure range of 0 to 5 kilopascals measures pressure relative to the local ambient atmospheric pressure. At 0 kPa output, the applied pressure equals atmospheric pressure. This is ideal for measuring small positive pressures or vacuums in systems like respiratory circuits, filter monitoring, or low-pressure pneumatic controls.

Yes, the Sencoch GZP6859D005KPP is factory calibrated. The integrated ASIC provides temperature compensation and outputs calibrated digital data, achieving an accuracy of ±2% of the full-scale (5 kPa) reading across the specified temperature range. No user calibration is typically required.

While the sensing element can respond to pressure, the standard SOP-6 package is not inherently sealed against liquid ingress. For liquid pressure applications, the sensor must be isolated using a compatible media-isolation diaphragm or seal to prevent damage from condensation or direct fluid contact, which is not specified for this model.
