Frequently Asked Questions

What is the output signal type of the GZP131-701A sensor?

The GZP131-701A provides an analog voltage output, typically in millivolts (mV), which is proportional to the applied gauge pressure. This raw signal requires external signal conditioning or amplification before being read by a microcontroller's ADC pin for digital conversion.

What is the recommended supply voltage and how do I connect it?

The sensor operates from a wide DC supply range of 1.8V to 15V. Connect the positive supply to the Vdd pin and ground to the Vss pin as per the datasheet. A stable, clean power supply is recommended, and decoupling capacitors near the sensor pins are advised for optimal noise performance.

Is this sensor suitable for measuring liquid pressure?

The GZP131-701A chip itself is a bare die in an SMD package and is not inherently sealed against liquids. For liquid pressure applications, the sensor must be properly packaged with a media-compatible barrier (like a gel fill or stainless steel diaphragm) to isolate the sensing element from direct fluid contact, preventing damage and corrosion.

How do I interpret the pressure reading from the analog output?

You must calibrate the sensor. Apply known pressures (e.g., 0 kPa and 700 kPa) and record the corresponding output voltages. The relationship is generally linear. Use these two points to establish a transfer function (mV/kPa) in your microcontroller firmware to convert the ADC reading into an accurate pressure value.
