====== Mars2 Monitor System ======

Mars2 is a remote monitoring system for reporting temperature, power, generator and other remotely sensed variables. The data is collected by an AVR processor at the remote site and transmitted via a UI broadcast packet to the home site.

==== Hardware ====


The remote hardware consists of:
  * 2 meter ground plane whip antenna
  * 2 meter FM radio
  * TinyTrak 4 (TT4) packet converter
  * AVR CPU

The remote AVR CPU has the following functions:
  * Two One Wire buses
  * Two optical interfaces for power sensing of the generator and utility power
  * RS232 interface to TT4 packet converter

The home hardware consists of:
  * 2 meter yagi antenna
  * 2 meter FM radio
  * TinyTrak 4 (TT4) packet converter
  * RS232 level converter
  * Kahlo 4 modified with 4 bit LCD, UART TX, RX outputs
