This document contains instructions and guidelines for the following: a quick- start demonstration and next steps, system overview and operations, hard- ware, firmware and ecosystem considerations, and engineering and manufac- turing testing. This guide applies to EmberZNet PRO 6.0 and later. The reference design comes preprogrammed with the Zigbee Z3Occupancy- Sensor sample application and is fully functional out of the box. All hardware design files are available within Simplicity Studio, Zigbee firmware application source code is available within the EmberZNet PRO stack, and Thread firm- ware application source is available within the Thread stack. Access to Zigbee and Thread stacks is available after purchasing and registering a wireless starter kit such as the SLWSTK6000B. Additional information about acquiring a wireless starter kit is available: UG249: Occupancy Sensor Reference Design Kit Users Guide (RD-0078-0201, RD-0099-0201) Introduction 1. Introduction The Silicon Labs Zigbee Occupancy Sensor Reference Design Kit, shown in the following figure is ready out of the box to demonstrate Zigbee occupancy sensing applications. Each unit is an ultra-low power, small, and cost-effective complete reference design based on the Zigbee 3.0 standard. This reference design kit features Silicon Labs EFR32MG1P232F256GM48 (RD-0078-0201) or EFR32MG12P432F1024GM48 (RD-0099-0201) Wireless Microcontroller (MCU), the Si7021 relative humidity and temperature sensor, and the Si1133 ambient light sensor. This document will provide a quick start demonstration and next steps, system overview and operation, hardware and firmware consid- erations, and engineering and manufacturing test. Figure 1.1. Zigbee Occupancy Sensor Reference Design The reference design can be directly integrated into a connected Zigbee home automation application, as shown below. All hardware design files and firmware source code are available. Figure 1.2. Zigbee Home Automation Application with Occupancy Sensors silabs.com Building a more connected world. Rev. 0.2 2
