Introduction
This document explains the functioning of the "smart monitoring system" and also serves as
a quick reference manual to operate the system. The smart monitoring system works on
®
ZigBee
wireless technology and measures temperature, humidity and light intensity of 9
remote and different locations simultaneously. The system also demonstrates the wireless
control of home appliances and can serve as a basis for many new systems.
The objective of this demonstration board is to design a complete system which
demonstrates the effectiveness of low data rate wireless solutions from ST in automating
various measurements for weather parameters. This system can be further interfaced to
take an appropriate action based on the parameters being monitored. The system can very
easily be modified to control various household appliances by suitable additional hardware.
This system uses various devices, the most relevant are the STM32x (microcontroller),
SPZB260 (ZigBee
STLM20 (temperature sensor) and various power supply components along with the battery
charger. The system has been designed taking future expandability into consideration.
The system can be powered up using:
■
External power supply
■
3.7 V Li-Ion battery
To summarize, the key features of the system are:
■
Wireless network
■
Monitoring of weather parameters (temperature, humidity, light intensity)
■
Wireless light control application
■
Node movement and simultaneous node movement detection
■
Various weather warning configurations and alarm messages

Page 7: System Features
The "smart monitoring system" has been designed and developed to give the user a number of original features which make this system unique. The system is comprised of one smart monitoring station (STEVAL-IFS014V1) and a maximum of 8 different smart monitoring nodes (STEVAL-IFS015V1). The smart monitoring station and all the nodes make a wireless STAR network and all the nodes communicate with the smart station using ZigBee protocol. -
Page 8: Single Node Movement Detection
0x0045 Note: Please note that these parameters have been chosen without any special consideration and can be changed later, but they should be the same for STEVAL-IFS014V1 and STEVAL- IFS015V1. Single node movement detection The system also detects movement or vibration of the active nodes in which case the buzzer sounds at the smart node and the smart station also receives this information. -
