light connection:

|

VCC -> 3V3 or 5V
|
||||
GND -> GND
|
||||
SCL -> SCL (A5 on Arduino Uno, Leonardo, etc or 21 on Mega and Due, on esp8266 free selectable)
|
||||
SDA -> SDA (A4 on Arduino Uno, Leonardo, etc or 20 on Mega and Due, on esp8266 free selectable)

ADD -> (not connected) or GND
|

|
||||
ADD pin is used to set sensor I2C address. If it has voltage greater or equal to
|
||||
0.7VCC voltage (e.g. you've connected it to VCC) the sensor address will be
|
||||
0x5C. In other case (if ADD voltage less than 0.7 * VCC) the sensor address will
|
||||
be 0x23 (by default).
