STEVAL-IHP002V2
STEVAL-IHP002V2
Smartplug system to measure and control AC loads based on the
STM32, ST7540 PLM and STPM01
Data brief
Features
■ Energy measurement by the STPM01
■ Power line communication by the ST7540 up to
4.8 kbps
■ USART connectivity or expansion connector
■ Output with two contacts (NO/NC) and
common contact for generic load
■ Designed to fit a standard "503" wall box
■ RoHS compliant
Description
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.
