Sencoch GZP160-040DR Pressure Sensor, -40Kpa~40Kpa Range, 1.8V~15V Supply, DIP-6 Package

The GZP160-040DR provides an analog voltage output that is proportional to the applied pressure. This signal can be directly connected to an analog-to-digital converter (ADC) pin on a microcontroller (e.g., Arduino, Raspberry Pi) for digital processing and monitoring.

This is a gauge pressure sensor, meaning it measures pressure relative to the ambient atmospheric pressure. A reading of 0 kPa corresponds to atmospheric pressure. It can measure both positive pressures (above atmospheric) and negative pressures (vacuum or suction below atmospheric) within its ±40 kPa range.

Apply a DC voltage between 1.8V and 15V across the designated V+ and GND pins on the DIP-6 package. The analog output pin will provide the voltage signal corresponding to the sensed pressure. Consult the sensor's datasheet for the specific pinout diagram to ensure correct wiring to your microcontroller's ADC input.

The sensor has a typical accuracy of ±2% of its full scale (±40 kPa). Accuracy can be influenced by factors like supply voltage stability, signal conditioning circuit design, and operating temperature. For best results, operate within the specified -30°C to 100°C range and consider performing a two-point calibration against known pressure references.
