Perfect for university projects
Bought this for a final year engineering project involving indoor navigation. The temperature compensation feature is very accurate. Documentation provided by the seller was helpful for getting started quickly.

Excellent precision for weather projects
I used this sensor for a DIY weather station and the readings are incredibly stable. The 24-bit resolution makes a noticeable difference compared to older models. Setup with Arduino was straightforward using the standard libraries.

Great for altitude hold
Works perfectly for my custom drone build. The altitude data is smooth and responsive. I deducted one star because the soldering pads are quite small, requiring a steady hand for wire attachment.

Low power consumption
Impressed by how little power this draws in sleep mode. Ideal for battery-operated IoT devices. The I2C communication is reliable even with long wires when proper pull-up resistors are used.

Good value module
The breakout board layout is logical and fits well on a breadboard. Readings match my professional barometer closely. Would prefer if it came with header pins pre-soldered, but that's a minor inconvenience.

Robust and reliable
Been running this sensor continuously for three months without any drift or issues. The library support for ESP32 is excellent. Highly recommend for anyone needing precise atmospheric data.
Q: Does this come with example code for ESP8266?
A: While the physical package does not include a USB drive, we provide links to GitHub repositories containing verified example code for ESP8266, ESP32, and Arduino in the product description section.
Q: What voltage should I use if powering via VIN?
A: If your module has a VIN pin with an onboard regulator, you can typically supply 5V. However, this specific breakout operates directly at 3.3V logic levels. Please ensure you supply between 1.71V and 3.6V to the VCC pin to avoid damage.
Q: What is the maximum cable length recommended for I2C connection?
A: For standard I2C speeds (100kHz), we recommend keeping cable lengths under 30cm without additional buffering. For longer distances, consider using an I2C extender or lowering the clock speed to improve signal integrity.
Q: Is this module compatible with Raspberry Pi?
A: Yes, the BMP388 module supports I2C protocol which is fully compatible with Raspberry Pi GPIO pins. You just need to enable the I2C interface in the Raspberry Pi configuration settings.
Q: Can this sensor be used underwater?
A: No, this specific breakout module is not waterproof or designed for submersion. It measures atmospheric pressure and should only be used in dry environments. The sensor chip itself is protected, but the board components are not.
