Multisensor PIR and Lux

[kchest]

I was finally able to combine the two example sketches (BH1750 Lux sensor and the HC-SR501. I thought I would share it in case it might help out another newbie like me ;-)

/**
 * 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
 *Light/Motion sensor using sketches from idefix and Henrik Ekblad
 * 
 * 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

Hey Kcest

Nice work!
Can you help me if I would like two PIR sensors in the same sketches.

thank you in advance, Tom
