XBee Shield (4)

/* XBee meshnet sensors
 * --------------------
 *
 * simulates the arrival of data from a mesh network 
 * with sensors each one of them sending 11 digital 
 * and 6 analog values. It is including one character 
 * per object to name the nodes and separates values 
 * with a symbol. It is not optimal for communication, 
 * but makes easy to understand how such a system will 
 * work in education
