Description

The GZP6857D005KPP utilizes a MEMS piezoresistive sensing core to translate applied pressure into a precise electrical signal. This signal is conditioned and digitized by an integrated ASIC, providing a stable, calibrated digital output via the I²C bus, eliminating the need for external analog-to-digital conversion and simplifying system design.

Engineered for reliability, the sensor is housed in a robust DIP-6 package capable of withstanding demanding environmental conditions across its full -30°C to +85°C operating range. Its low-power architecture makes it particularly suitable for always-on, portable, or wireless sensing applications where energy efficiency is critical.

Key Features

  • High-Precision MEMS Sensing: Delivers accurate and repeatable pressure readings with a typical accuracy of ±2% across the 0–5 kPa gauge range.
  • Ultra-Low Power Operation: Features a minimal 100nA standby current, enabling deployment in long-life, battery-powered monitoring systems.
  • Digital I²C Communication: Provides a two-wire digital interface for easy connection to most microcontrollers and single-board computers, reducing noise susceptibility compared to analog outputs.
  • Extended Temperature Range: Maintains specified performance in harsh environments from -30°C to +85°C.
  • Compact & Standard Footprint: The DIP-6 package allows for straightforward through-hole PCB mounting and integration.
  • Optimized Performance-to-Cost Ratio: Offers a high-value build combining measurement accuracy, low power, and digital convenience for cost-sensitive yet performance-driven applications.

Applications

  • Portable medical diagnostic equipment for non-invasive pressure monitoring (e.g., CPAP machines, spirometers).
  • Smart home appliance control systems for fluid level detection, filter monitoring, or airflow sensing.
  • Industrial IoT (IIoT) sensor nodes for low-pressure differential monitoring in ventilation systems.
  • Wearable health and fitness devices requiring barometric altitude tracking or respiration rate sensing.
  • Battery-operated environmental data loggers for atmospheric pressure trend analysis.

Frequently Asked Questions

What is the absolute maximum supply voltage for this sensor?

The Sencoch GZP6857D005KPP is designed for a nominal 3.3V supply. Exceeding this voltage, typically beyond 3.6V, can permanently damage the internal MEMS and ASIC components. Always ensure your power source is regulated to 3.3V ±5% for reliable and safe operation.

How do I connect and read data from the I2C interface?

Connect the sensor's VDD to 3.3V, GND to ground, SDA to your microcontroller's SDA line, and SCL to the SCL line. Pull-up resistors (typically 4.7kΩ) are required on both SDA and SCL lines if not provided by your host board. You can then use standard I2C library commands to read the device's I2C address (consult datasheet) and request pressure data registers.

Is this sensor suitable for measuring liquid pressure?

No, the GZP6857D005KPP is a gauge pressure sensor with a port designed for dry, non-corrosive gases like air. Its sensing diaphragm is not isolated from the media port. Direct contact with liquids, conductive fluids, or corrosive gases can damage the sensor and invalidate its readings.

Does the sensor require calibration, and what is its long-term stability?

The sensor is factory calibrated, providing the stated ±2% accuracy out-of-the-box for typical applications. For critical measurements, user-level calibration against a known reference can improve accuracy. Long-term stability is influenced by operating conditions; the MEMS element is designed for minimal drift under normal use within its specified temperature and pressure ranges.
