* The MySensors Arduino library handles the wireless radio link and protocol
|
|
* between your home built sensors/actuators and HA controller of choice.
|
|
* The sensors forms a self healing radio network with optional repeaters. Each
|
|
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
|
|
* network topology allowing messages to be routed to nodes.

* REVISION HISTORY
|
|
* Version 1.0 - idefix
|
|
*
|
|
* DESCRIPTION
|
|
* Arduino BH1750FVI Light sensor
|
|
* communicate using I2C Protocol
|
|
* this library enable 2 slave device addresses
|
|
* Main address 0x23
|
|
* secondary address 0x5C
|
|
* connect the sensor as follows :
|
|
*
|
|
* VCC >>> 5V
|
|
* Gnd >>> Gnd
|
|
* ADDR >>> NC or GND
|
|
* SCL >>> A5
|
|
* SDA >>> A4
