  4. CRON job (PHP script)

1. Hardware

You need to connect the different sensors to the Arduino board. You may either use breadboard with some cords or solder everything onto a shield.

The light sensor

Follow the instructions from the URL beneath but connect the light sensor to the analog pin 0.

Humidity sensor

Follow the instructions from the URL beneath but connect the humidity sensor to the analog pin 1.

Baromethric pressure & temperature sensor

Follow the instructions from the URL beneath.

2. Microcontroller

Next you need to upload the controller sketch to the Arduino. In order to be able to compile it, you have to install the BMP085 library into the Arduino IDE. You can get it here:

http://code.google.com/p/bmp085driver/

3. Database

All data captured by the CRON script will be put into an RRD database. For this, you need to setup 4 files. Move into the directory where you want them to stay and execute the 4 commands:

rrdtool create arduinoDaily.rrd --start N --step 180 DS:temperature:GAUGE:360:-10:60 DS:pressure:GAUGE:360:900:1200 DS:humidity:GAUGE:360:0:100 DS:light:GAUGE:360:0:100 RRA:MIN:0.5:1:480 RRA:MAX:0.5:1:480 RRA:AVERAGE:0.5:1:480 

rrdtool create arduinoWeekly.rrd --start N --step 180 DS:temperature:GAUGE:360:-10:60 DS:pressure:GAUGE:360:900:1200 DS:humidity:GAUGE:360:0:100 DS:light:GAUGE:360:0:100 RRA:MIN:0.5:6:560 RRA:MAX:0.5:6:560 RRA:AVERAGE:0.5:6:560 

rrdtool create arduinoMonthly.rrd --start N --step 180 DS:temperature:GAUGE:360:-10:60 DS:pressure:GAUGE:360:900:1200 DS:humidity:GAUGE:360:0:100 DS:light:GAUGE:360:0:100 RRA:MIN:0.5:20:720 RRA:MAX:0.5:20:720 RRA:AVERAGE:0.5:20:720 

rrdtool create arduinoYearly.rrd --start N --step 180 DS:temperature:GAUGE:360:-10:60 DS:pressure:GAUGE:360:900:1200 DS:humidity:GAUGE:360:0:100 DS:light:GAUGE:360:0:100 RRA:MIN:0.5:240:730 RRA:MAX:0.5:240:730 RRA:AVERAGE:0.5:240:730
