Smartplug description

The smartplug coordinator is connected via an SPI to the STM3210C-EVAL through an “Ad-

Hoc” adapter.

In Figure 1 it is possible to take a quick look at the STM3210C-EVAL board and a smartplug

node block diagram.

Figure 1.

STM3210C-EVAL block scheme

An adapter is connected to the extended connectors CN8 and CN9 on the STM3210C-

EVAL (for more detailed information please refer to the UM0600 user manual), it allows the

connection of a ZigBee smartplug coordinator and the I2C/RF dual interface EEPROM

M24LR64-r. The Gerber files of the adapter board are included in the setup package of this

project.

The ZigBee smartplug board can be used as a guide to build a home/building automation

subsystem for energy management. In a typical application, the board is plugged into an

electrical wall socket and supplies an electrical load, monitoring the energy consumption;

using several smartplugs it is possible to monitor and control the home/building energy

consumption socket by socket. The board includes the following functions, shown in the

block diagram of Figure 2:

●

Energy measurement

●

Load differential current

●

Load driving by relay or TRIAC (dimming)

●

ZigBee communication capability.
