CFSensor GZP6895A100KPP50H Differential Pressure Sensor, 0-100kPa Range, 5V Analog Output, ROHS

The sensor provides a ratiometric analog voltage output, typically 0-5V, directly proportional to the applied differential pressure across its 0-100 kPa range. This output can be directly connected to a microcontroller's analog-to-digital converter (ADC) pin for measurement.

The sensor requires a single 5V DC power supply. It is critical to provide a stable, low-noise 5V source, as supply voltage variations can affect the accuracy of the analog output signal. Ensure your power supply can deliver the necessary current, typically in the low mA range.

For Arduino: Connect the sensor's VCC to 5V, GND to GND, and the analog output pin to any analog input (e.g., A0). Use the `analogRead()` function. For Raspberry Pi (which lacks native analog inputs), you will need an external ADC module (like an ADS1115) to convert the sensor's 0-5V analog signal to a digital value the Pi can read via I2C.

Yes, as a true differential pressure sensor, it can measure pressure differences in either direction. A positive voltage output indicates pressure on Port 1 is higher than Port 2. A voltage below the zero-pressure offset (typically ~2.5V for a 5V supply) indicates the opposite, allowing measurement of negative differential pressure within the specified range.
