Frequently Asked Questions

What is the output signal of the MPX5700DP pressure sensor?

The MPX5700DP provides a ratiometric analog voltage output with a sensitivity of 6.4 mV per kilopascal (kPa). This high-level output is designed for direct connection to a microcontroller's analog-to-digital converter (ADC) input without requiring additional amplification in most applications.

What is the difference between gauge, absolute, and differential pressure types?

This MPX5700DP model is configured for differential pressure measurement. It measures the difference in pressure applied between its two ports, unlike an absolute sensor (which references a vacuum) or a gauge sensor (which references atmospheric pressure). This makes it suitable for applications like filter monitoring or flow measurement where the pressure drop across a component is critical.

How do I interface the MPX5700DP with an Arduino or other microcontroller?

Connect the sensor's Vout pin to an analog input pin on your microcontroller (e.g., Arduino A0). Supply power (Vs) between 4.75V and 5.25V, ensuring the ground (GND) pin is connected. The output voltage will be proportional to the applied differential pressure, which your code can read via the ADC and convert to kPa using the 6.4 mV/kPa sensitivity.

What is the accuracy and operating temperature range of this sensor?

The sensor has a typical accuracy of ±2.5% of Full Scale (FS) over the compensated temperature range. It is designed to operate reliably across an extended temperature range from -40°C to +125°C, making it suitable for use in harsh automotive and industrial environments.
