The STEVAL-IHP002V2 demonstration board 
implements a PLM smartplug node which allows 
monitoring the energy consumption of a mains 
plug and controlling any kind of load in on/off 
mode through a relay.

The board is based on the STM32F103CB 
microcontroller, the ST7540 PLM module and the 
STPM01 mono-phase energy metering IC.

The board is designed to fit a standard "503" wall 
box.

The voltage, current, power, active energy and the 
output status can be sent to a PLM data 
concentrator through a power line communication 
network on request. Moreover, if the power 
consumption changes, it is sent asynchronously 
to the data concentrator.
