Rev. 0.4 UG120: Zigbee Capacitive Sense Dimmer Switch Reference Design (RD-0039-0201) Kit User s Guide Introduction 1. Introduction This document describes the Silicon Labs Zigee HA 1.2-based capacitive sense dimmer switch reference design (Figure 1.1 Zigbee Capacitive Sense Dimmer Switch Reference Design on page 2) using the EM3587 wireless microcontroller (MCU) which reduces development costs and enables faster time to market for customers. This reference design can be directly integrated into a connected zigbee home automation lighting application shown in Figure 1.2 Connected Capacitive Sense Dimmer Switch Application Example on page 2. The capacitive sense dimmer switch comes preprogrammed and ready to demonstrate out of the box. All hardware design files and firmware application source code are available. Figure 1.1.
