1. Introduction

There is an increasing desire in the market for a standards-driven, low-cost, and low-power wireless home automation system. Silicon

Labs has released an ultra-low power, small, and cost-effective complete reference design based on ZigBee HA 1.2 standard that focu-

ses on contact sensors that can be used for window or door sensing (Figure 1.1 ZigBee Contact Sensor Reference Design on page

1). This ZigBee contact sensor reference design kit features Silicon Labs’ EM3587 ZigBee Pro Wireless Microcontroller (MCU) and

the Si7053 temperature sensor. The reference design can be directly integrated into a connected ZigBee home automation application

as shown in Figure 1.2 ZigBee Home Automation Application with Contact Sensors on page 1. The contact sensor boards come pre-

programmed and fully functional out of the box. All hardware design files and firmware application source code are available.
