Documentation lacking
Sensor works but had to search online for the library setup instructions.
5 FAQ
Q: Is this compatible with ESP8266?
A: Yes, it works perfectly with ESP8266 modules using 3.3V logic.
Q: Is the module waterproof?
A: No, the PCB is not waterproof. Please use an enclosure for outdoor use.
Q: Can I use 5V logic directly?
A: The module supports 5V power, but I2C lines should be 3.3V for safety.
Q: Does it measure altitude?
A: It measures pressure, which can be converted to altitude using standard formulas.
Q: What is the I2C address?
A: The default address is 0x76, but it can be changed to 0x77 via the SDO pin.
