Sencoch GZP6859A005KPP50K Analog Pressure Sensor, 0-5 kPa Range, 5V Supply, SOP-6 Package

The sensor provides an analog voltage output that is linearly proportional to the applied gauge pressure. The output is ratiometric to the 5V supply voltage, meaning the full-scale output voltage will scale directly with the supply voltage, simplifying interface with analog-to-digital converters (ADCs) on microcontrollers like Arduino or Raspberry Pi.

The sensor is designed for a nominal 5V DC supply. Under typical operating conditions, it draws a standby current of approximately 1.8mA. It is critical to provide a stable, low-noise 5V power source to ensure accurate and consistent analog output readings from the sensor.

Connect the sensor's VCC and GND pins to a stable 5V power source and ground. The analog output pin should be connected directly to an ADC input channel on your microcontroller (e.g., Arduino, STM32, ESP32). No external signal conditioning is typically required due to the ratiometric output, but a simple RC low-pass filter may be added to reduce electrical noise if needed.

This is a gauge pressure sensor. It measures pressure relative to the ambient atmospheric pressure at the sensor's location. It is suitable for applications where you need to measure pressure differentials relative to the local environment, such as in airflow systems, medical respiratory circuits, or appliance pressure chambers.

The sensor comes in a surface-mount SOP-6 package with a 2.54mm pin pitch. It is intended for reflow soldering onto a PCB. Handle with standard ESD precautions. Ensure the pressure port is correctly oriented and sealed to the measured medium, avoiding exposure to contaminants, moisture, or pressures exceeding the 5 kPa maximum range.
