Where is the information on which sensors and power chords to purchase?

Hello,
I may just be missing it, however I cannot seem to find a section on the website or manual on which sensors to purchase. I just see in the system cost section:
Data Logger, SD card, and power cable

$50/site

Micro-sensors for temperature, pressure, humidity, wind, light, and precipitation

$100/site

I am just a little confused on where the information for which micro sensors, data logger and power cable to purchase. Thank you so much for your help!
