CactusFarm is our low bandwidth sensor network based on the jeelab RF12 modules. Runs on 868Mhz and allows pumping of data into cacti graphs.


RMF12pi "hub" is an RF module with python daemon that converts the serial data from a RMF12pi to a webserver in a format suitable for grabbing with cacti. Information can be found on the github readme.

digraph rfboard{
  hub [label="RMF12pi hub",shape=box];
  cacti [label="graphs",shape=box];
  node1 [label="node 1",shape=box];
  node2 [label="node 2",shape=box];
  node3 [label="node 3",shape=box];
  node1 -> hub;
  node2 -> hub;
  node3 -> hub;
  hub -> node1;
  hub -> node2;
  hub -> node3;
  hub -> cacti;

} </graphviz>
