Frequently Asked Questions

What is the operating voltage range for the GZP6891D001KPW sensor?

The sensor operates from a supply voltage of 2.7V to 5.5V DC. This wide range makes it directly compatible with both 3.3V and 5V microcontroller systems, such as those based on Arduino, ESP32, or Raspberry Pi, without requiring a level shifter.

How do I interface with this pressure sensor?

The sensor provides a digital I²C interface. You will need to connect the SDA and SCL lines to your microcontroller, along with power (VDD) and ground (GND). Refer to the official datasheet for the specific I²C address and communication protocol details for reading pressure data.

What does the ±1 kPa pressure range mean?

A range of -1 kPa to +1 kPa indicates the sensor can measure both positive and negative differential pressure. A positive reading means Pressure Port 1 is higher than Port 2, while a negative reading means Port 2 is higher. It is designed for very low-pressure applications like airflow sensing.

Is this sensor suitable for medical device development?

Yes, its primary applications include medical and healthcare equipment, such as respiratory devices, due to its high sensitivity and accuracy in a low-pressure range. Its digital output and compact SOIC package are well-suited for integration into portable and embedded medical diagnostics.
