STEVAL-IHP004V1

High-end smartplug systems to measure and control AC loads

based on the SPZB32W1A2.1, STPM10, T2035H and M24LR64

Data brief

Description

The STEVAL-IHP004V1 demonstration board is a

smartplug based on the SPZB32W1A2.1 module

which integrates the STM32W108 microcontroller

with IEEE-802.15.4 integrated radio and 32-bit

ARM Cortex-M3 core.

The STPM10 energy metering IC is used for

energy measurement while the AC load can be

controlled by a 16 A relay supporting soft-switch

by the T2035H TRIAC.

The STEVAL-IHP004V1 demonstration board is a

node of an RF network which allows the final user

to monitor and manage the plugged load energy

consumption. The node personalization is

supported by the M24LR64 dual interface

EEPROM.

The introduction of the dual interface EEPROM

enables RF communication with RFID readers or

ISO15693-capable NFC phones, allowing offline

programming of the smart plug’s

parameters/profile, as well as download of

events/logs.

The STEVAL-IHP004V1 demonstration board has

been developed in order to provide a guideline to

build a home/building automation subsystem for

energy management and sub-metering. It is

designed to fit the dimensions of a standard box

for wall installation and easy integration into

home/building electrical plants.

The current, power, energy and other info related

to the electrical load connected to the smartplug

board are sent to an IEEE-802.15.4 data

concentrator through the home/building RF

network.
