1. A string monitor comprising:
(a) a base unit including;
(i) a power supply; and(ii) a base unit controller arranged to communicate a datum and an instruction; and (b) a sensor module including;
(i) a power bus conductively connectable to said power supply of said base unit such that a sensor module controller of said sensor module obtains its processing power for operating only from said power bus which only obtains said processing power from said power supply of said base unit;(ii) a data bus communicatively connectable to said base unit controller, said data bus and said power bus arranged for selective connection to a second sensor module;(iii) a sensor to sense at least one of a voltage at a voltage source and a direct current in a conductor; and(iv) said sensor module controller arranged to quantify at least one of said voltage and said direct current sensed by said sensor and communicatively connected to said data bus to exchange at least one a datum quantifying at least one of said voltage and said direct current and an instruction with said base unit controller;(v) said sensor module including a connector suitable to interconnect said sensor module to another sensor module to provide processing power to said another sensor module.
