The SDP600 series of digital differential pressure sensors are high-value digital differential pressure sensors designed for mass volume applications. The series features Sensirion’s patented CMOSens® sensor technology, which provides excellent accuracy, repeatability and long-term stability.
The SDP600 series is a family of low‑cost digital differential pressure sensors from Sensirion, designed for high‑volume applications such as medical, HVAC, automotive, and process automation. The sensors measure air and non‑aggressive gases with high accuracy and feature a 2‑wire I2C digital interface.
Key features include operation from a 3.3 V supply, selectable pressure ranges up to +500 Pa, 12‑bit resolution, temperature compensation, and robust mechanical designs suitable for wave‑soldering. The datasheet also covers OEM customization options, mechanical mounting details, and handling instructions.
| Pressure range | −500 Pa to +500 Pa (up to +125 Pa or +25 Pa for low‑pressure versions) |
|---|---|
| Supply voltage | 3.3 V DC (low‑power version 3.0 V DC) |
| Zero‑point accuracy | 0.2 Pa (0.1 Pa for some variants) |
| Response time | 4.6 ms typical at 12‑bit resolution |
| Operating temperature | −20 °C to +80 °C |
| Current drain | < 6 mA typical (low‑power < 400 µA) |
| Weight | < 6 g |
The sensors operate from a 3.3 V DC supply, while low‑power versions can run at 3.0 V DC.
The default I2C address is 64 (binary 1000 000).
It measures differential pressure from –500 Pa to +500 Pa (with low‑pressure variants down to –500 Pa to +125 Pa or +25 Pa).
The sensor includes a digital temperature compensation circuit integrated on the CMOSens® chip, requiring no external compensation.
