Multisensor PIR and Lux



  • 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
