Sensor Specifications

Detail

Maximum primary current: 100A
Turns ratio: 1:2000 approximately
Minimum resolution: 130mA approximately
Measurement range: 500mA ~ 40A

Measurement Process

The current clamp is a low cost sensor that outputs a current proportional to the current in the primary circuit. That current (related with the primary current through a 1:2000 ratio) is converted into voltage through a load resistor obtaining a signal readable by the mote’s analog-to-digital converter.
