Frequently Asked Questions

What is the supply voltage for the HSCDRRN001ND2A3 sensor?

The sensor is designed for a 3.3V DC supply. Operating outside this specified voltage may damage the internal circuitry or lead to inaccurate readings. Always ensure your power source is regulated and stable.

How do I interface this sensor with an Arduino or Raspberry Pi?

The sensor communicates via the I2C protocol. Connect the SDA and SCL pins to the corresponding I2C pins on your microcontroller, along with 3.3V power and ground. You will need to use a library or write code to read the pressure data from the sensor's I2C address.

What type of tubing is compatible with the barbed ports?

The dual radial barbed ports are designed for standard flexible tubing with an inner diameter suitable for the barb size (typically 2-3mm ID). Ensure tubing is pushed on securely to prevent leaks, which is critical for accurate differential pressure measurement.

What is the difference between differential and gauge pressure measurement?

This sensor measures differential pressure, the difference between two applied pressures (P1 and P2). It is not referenced to atmospheric pressure. For gauge pressure (relative to atmosphere), one port must be vented to the ambient environment.
