Tom's Life Bits

TG XB Enviro

This Arduino based computer was designed to monitor porch temperature, porch heater, outdoor temperature, greenhouse temperature and greenhouse heater. The readings will be sent as a packet via Xbee to Meister 2 for display on a web page. Meister 2 will take care of feeding Pachube as well as the web page serving.

RJ45 inputs on TG XB Enviro:

* OW1 4-Porch temp, 6-porch heater, Gnd = 5, 3
* OW2 4-Greenhouse temp, 6-greenhouse heater. Gnd = 5, 3
* OW3 4-Outdoor temp & humidity, 6-barometer, Gnd = 5, 3
* spare RJ45

Twisted pairs in cat 5 = 4 & 5, 6 &3

Currently OW3 & OW4 notused
