Solid build quality

The red PCB looks nice and the components seem well-soldered. One unit had a slightly noisy output, but the other five worked perfectly.

Easy to integrate

Setup took less than 10 minutes. The pinout is standard, making it compatible with most breadboards and microcontrollers I own.

Good value for altitude sensing

Used this for a small weather balloon project. It's accurate enough for hobbyist use, though calibration is required for precise readings.

5 FAQ

Q: Is the 5V input safe for long-term use?

A: Yes, the module includes a voltage regulator and can safely operate at 5V continuously within the specified temperature range.

Q: Is this sensor waterproof for submersion?

A: The sensor module itself is not fully waterproof for deep submersion. It is designed to measure water level via air pressure in a tube or detect surface contact. Please protect the electronics from direct water exposure.

Q: Does this come with a library for Arduino?

A: We do not provide a proprietary library, but this sensor works with standard analog read functions. Many community-created libraries for generic pressure sensors are compatible.

Q: Can this measure negative pressure (vacuum)?

A: No, this specific model is designed for gauge pressure ranging from 0 to positive values. It is not suitable for measuring vacuum or negative pressure.

Q: What is the maximum cable length recommended?

A: For optimal signal integrity, we recommend keeping the connection cables under 1 meter. Longer cables may introduce noise to the analog signal.
