High Precision as Advertised

Impressed by the stability over temperature changes. We integrated this into a flow measurement system and it hasn't drifted.

Solid sensor, minor wiring note

Works well in our testing rig. Just note that the analog output needs a stable reference voltage. Otherwise, very reliable differential readings.

Good but docs are sparse

The sensor itself works fine, but finding the exact register map for I2C took some digging. Would be nice to have a clearer datasheet link.

Perfect for HVAC Monitoring

Used this for a custom HVAC dashboard. The I2C output is clean and easy to read with a microcontroller. Accuracy seems spot on compared to my calibrated meter.

Reliable for Automation

Bought five units for a batch of controllers. All arrived working and consistent. Great value for the precision level.

5 FAQ

Q: Is this compatible with Arduino Uno?

A: Yes, the I²C interface works perfectly with Arduino Uno using standard Wire library.

Q: What is the maximum overpressure it can withstand?

A: The module can withstand up to 2x the full-scale range without damage, but accuracy is not guaranteed beyond the rated range.

Q: Does it require external calibration?

A: No, the APR10 comes factory calibrated. However, system-level calibration is recommended for critical applications.

Q: What is the length of the pressure ports?

A: The barbed fittings are standard 6mm, suitable for common pneumatic tubing sizes.

Q: Can I use this outdoors?

A: The module is not IP-rated for water resistance. It should be housed in an enclosure if used outdoors.
