Reliable for low-pressure gas monitoring

We deployed ten of these modules for monitoring gas flow in our testing rig. They have been running for three months without drift. The build quality feels robust.

Perfect for drone airspeed sensing

Lightweight and accurate. I used this to measure differential pressure for airspeed estimation on a custom drone. The response time is fast enough for real-time control loops.

Excellent precision for HVAC projects

I used this sensor for a custom HVAC monitoring system. The I2C communication is stable, and the readings are very consistent compared to our calibrated lab equipment. Highly recommended for industrial prototyping.

Great value, easy integration

Integrated easily with my ESP32 project. The voltage output option is a nice backup if I2C acts up. Only giving 4 stars because the documentation could be slightly more detailed on calibration steps.

Solid performance in varying temps

Tested this in an environmental chamber. It held its accuracy well across the specified temperature range. The voltage output is clean with minimal noise.

5 FAQ

Q: How do I calibrate the zero point?

A: You can perform a zero-point calibration by sending the specific command sequence via I2C while ensuring both pressure ports are open to the same atmospheric pressure. Details are in the user manual.

Q: Can I use this with a 3.3V microcontroller like the ESP8266?

A: Yes, the APR10 operates within a 3.3V to 5.5V range, making it fully compatible with 3.3V logic microcontrollers without needing a level shifter.

Q: What is the default I2C address?

A: The default I2C address is typically 0x28. Please refer to the specific datasheet included in the download section for confirmation regarding your batch.

Q: Is this sensor suitable for measuring liquid pressure?

A: No, the APR10 is designed specifically for gas and air differential pressure measurements. Using it with liquids may damage the internal sensing element.

Q: Does this module come with the connecting tubes?

A: No, the module includes the sensor and PCB only. You will need to source compatible silicone tubing separately based on your specific port requirements.
