Frequently Asked Questions

What is the operating voltage range for the ADP2000 sensor?

The ADP2000 operates from a 3.3V to 5V DC power supply. This wide range makes it directly compatible with most 3.3V and 5V logic microcontrollers and development boards like Arduino, Raspberry Pi, and ESP32 without requiring a level shifter.

What communication protocol does the ADP2000 use?

The ADP2000 provides a digital I2C (Inter-Integrated Circuit) interface. This two-wire serial protocol allows for easy connection to a host microcontroller for reading differential pressure and temperature data, simplifying system wiring compared to analog sensors.

What gases can the ADP2000 sensor measure?

The ADP2000 is designed to measure the differential pressure of clean, dry, non-corrosive gases such as air, nitrogen, and oxygen. It is not suitable for measuring liquids or aggressive, corrosive gases that could damage the internal MEMS sensing element.

How fast is the sensor's response time?

The ADP2000 features a very fast response time of 10 milliseconds. This rapid update rate allows it to capture quick pressure transients and dynamic changes effectively, making it suitable for applications requiring real-time monitoring and control.
