Introduction
GY-91 and many other Arduino digital sensors use I2c protocol to send the data using digital protocols.
Theory
From Arduino IDE find “File → Examples → Wire → i2c_scanner”. Using that script, you can find out what I2C devices are connected to your Arduino Board.
I have connected the GY-91 sensor which has
- MPU 9250 sensor and
- BMP280 sensor.
The other address 0x68 is for the other sensor and the other 0x76 is for the other sensor.
