Reliable indoor/outdoor monitoring

I integrated this into my home automation system to track barometric trends for storm prediction. It has been running for three months without a single dropout or error.

Good accuracy, compact size

Used this for altitude hold on a small quadcopter. It's lightweight and responsive. Only giving 4 stars because the soldering pads are a bit small for beginners, but performance is solid.

Perfect for weather station projects

This module works flawlessly with my ESP32 setup. The I2C address was easy to find, and the library support is excellent. Readings are stable and match my local weather station data very closely.

Great value for money

Bought this for a university physics project involving fluid dynamics. It handled the pressure changes perfectly and the documentation provided by the seller helped me get started quickly.

Exceeded expectations

Very sensitive sensor. I can detect elevation changes of less than a meter just by moving it from the floor to the table. Highly recommended for anyone doing environmental sensing.

Works well with Python scripts

Connected easily to a Raspberry Pi Zero. The data output is clean and requires minimal filtering. Would have preferred a built-in voltage regulator for wider input tolerance, but 3.3-5V is standard enough.

5 FAQ

Q: What is the default I2C address?

A: The default I2C address is typically 0x76 or 0x77 depending on the specific batch configuration. Our guide includes a scanner sketch to identify the address automatically.

Q: Does it support 3.3V logic levels directly?

A: Yes, the module operates natively at 3.3V and is 5V tolerant on the power input, making it safe to connect directly to 3.3V microcontrollers like the ESP32.

Q: Does this module come with example code for Arduino?

A: Yes, we provide a link in the package documentation to a GitHub repository containing comprehensive Arduino and Python examples.

Q: Is the pin header pre-soldered?

A: No, the pin header strip is included separately in the package to allow for flexible mounting options. You will need to solder them yourself.

Q: Can this sensor be used underwater for liquid level measurement?

A: The sensor chip itself can measure pressure exerted by liquids, but the PCB board is not waterproof. You must house it in a waterproof enclosure with a pressure port to use it for liquid level applications.
