Sencoch GZP160-201S Pressure Sensor -100kPa~200kPa, SOP-6 Package

The GZP160-201S is a gauge pressure sensor. This means it measures pressure relative to the ambient atmospheric pressure. Absolute pressure sensors measure relative to a perfect vacuum, while differential sensors measure the difference between two pressure ports. The GZP160-201S is ideal for applications where you need to know the pressure inside a system compared to the outside environment, such as in HVAC ductwork or medical respiratory devices.

The sensor provides an analog voltage output. Connect the VCC pin to a stable power supply between 1.8V and 15V (ensure it matches your microcontroller's logic levels, e.g., 5V or 3.3V). Connect the GND pin to common ground. The signal output pin should be connected directly to an analog input (ADC) pin on your microcontroller. You will need to map the ADC reading to the pressure range using the sensor's transfer function, typically found in its datasheet.

This range indicates the sensor can measure both vacuum (negative pressure) and positive pressure. The -100 kPa lower limit means it can detect a vacuum level equivalent to 100 kPa below atmospheric pressure. The +200 kPa upper limit means it can measure positive pressure up to 200 kPa above atmospheric pressure (approximately 2 bar or 29 psi). This makes it suitable for applications involving suction, low-pressure monitoring, or moderate over-pressure conditions.

The GZP160-201S is a piezoresistive MEMS sensor typically designed for non-corrosive, dry air or gas media. Its SOP-6 package is not inherently sealed for liquid immersion or direct contact with conductive or corrosive fluids. For liquid pressure measurement, you would typically use a sealed pressure transducer with a stainless steel diaphragm and a liquid-compatible port. Always consult the sensor's datasheet for media compatibility specifications before installation.
