STEVAL-IHP002V1 STMicroelectronics

STEVAL-IHP002V1 SmartPlug systems to measure and control AC loads, based on the STM32, ST7540 PLM, and STPM01 Data brief Features Energy consumption monitoring PLM communication On/Off or dimming configuration CENELEC band C compliant System setting by RS232 RoHS compliant Description The STEVAL-IHP002V1 demonstration board is a SmartPlug based on the STM32F10x STEVAL-IHP002V1 microcontroller, ST7540 PLM, and STPM01 energy metering ICs. The board is a node of a PLM network which allows the final user to monitor and manage the plugged load energy consumption, and can work in conjunction with the STEVAL-IHP003V1 used as a data concentrator for connection to a PC. The board has been developed as a guideline to build a home/building automation subsystem for energy management. 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 information related to the electrical load connected to the SmartPlug board are sent to a PLM data concentrator (such as the STEVAL- IHP003V1) through the home/building PLM network. A protocol stack has been implemented to allow node communication it includes a PHY layer with FEC, a MAC layer with CSMA/CA and ACK, and a network layer with static addressing and routing topology.
