Sencoch GZP6859A101KPP50K Pressure Sensor, 0-100 kPa Gauge, SOP-6-2.54mm Package

The Sencoch GZP6859A sensor is designed for a nominal supply voltage of 6.5V DC. It is critical to adhere to this voltage specification to ensure rated accuracy and prevent damage to the internal MEMS piezoresistive bridge. Operating outside this specified voltage may lead to signal inaccuracy or sensor failure.

The sensor provides an analog voltage output proportional to the applied pressure. Connect the output pin directly to an Analog-to-Digital Converter (ADC) input on your microcontroller (e.g., an Arduino analog pin). Ensure the sensor's ground is shared with the MCU. You will need to map the ADC reading (e.g., 0-1023 for a 10-bit Arduino ADC) to the 0-100 kPa pressure range using a calibration factor, typically defined in the sensor's datasheet.

This specific model (GZP6859A101KPP50K) measures gauge pressure, meaning its output is referenced to the ambient atmospheric pressure. A reading of 0 kPa indicates pressure equal to the surrounding atmosphere. It is not suitable for measuring absolute pressure (referenced to a vacuum). For applications like barometric pressure measurement, an absolute pressure sensor variant would be required.

While the MEMS sensing element itself is sensitive to pressure media, the standard package is typically intended for clean, dry, non-corrosive gases like air. Direct contact with liquids may damage the sensor unless specifically noted as liquid-media compatible in the official datasheet. For liquid pressure applications, ensure proper isolation via a diaphragm or use a sensor variant explicitly rated for liquid media.
