Frequently Asked Questions

What are the output interfaces of the SM5391 pressure sensor?

The SM5391-BCE-S-012.00-451 provides two independent output interfaces: a conditioned analog voltage output and a calibrated 16-bit digital output via the I2C communication protocol. This allows direct connection to analog ADCs or digital communication with microcontrollers like Arduino, Raspberry Pi, or STM32 without additional signal conditioning.

What is the operating voltage range for this sensor?

This sensor requires a supply voltage between 4.75V and 5.25V DC. It is designed for stable operation at a nominal 5V, making it directly compatible with standard 5V logic systems, USB power, and common microcontroller development boards. Ensure your power supply is within this specified range for guaranteed accuracy and performance.

How do I connect the pneumatic tubing to this sensor?

The sensor is housed in a SOIC-16 package that integrates two axial barbed ports. Standard flexible tubing (with an inner diameter matching the barb size) can be pushed directly onto these ports for a secure, leak-resistant connection. Ensure tubing is properly seated and consider using hose clamps for high-vibration or high-pressure differential applications.

Is this sensor suitable for medical device applications?

Yes, the SM5391 is engineered for demanding applications like CPAP machines and ventilators, offering high accuracy (±1% FS digital) and reliability across a -20°C to +85°C temperature range. However, for medical device integration, always consult the full TE Connectivity datasheet for detailed performance specifications, validation requirements, and any necessary regulatory certifications for your specific end-use.
