Silicon Labs’ two wireless occupancy sensor and smart outlet reference designs for the home automation market include all of the hardware, firmware and software tools required to create feature-rich, future-proofed connected home products based on the company’s ZigBee “Golden Unit” Home Automation (HA 1.2) software stack and multiprotocol Wireless Gecko system-on-chip (SoC) portfolio. The occupancy sensor reference design is a compact, pre-certified ZigBee HA 1.2 solution featuring a wirelessly connected passive infrared sensor along with ambient light and temperature/relative humidity sensors. The occupancy sensor’s small, battery-powered design (the size of two AAA batteries) is so energy efficient it can operate for up to five years before battery replacement. The sensor’s detection range extends up to 12 meters (nearly 40 feet) with a 90 degree viewing window.
The smart outlet reference design is a complete, pre-certified solution for a wirelessly controlled outlet plug that can be used to power and control a wide range of home and building automation products. The design includes:
• Built-in diagnostics and metering with a user-friendly web interface for wireless control and current/voltage monitoring, easily accessible from mobile devices
• A wide ac voltage range (110-240 V) for global use along with a robust 15 A load current
• Integrated high-accuracy sensors: ambient light and temperature/humidity
• Compact design: 6.5 cm x 6.5 cm x 4.0 cm
Both reference designs include Silicon Labs’ EFR32MG Mighty Gecko SoC and require the ZigBee gateway or an HA 1.2-compliant gateway. System configuration, debugging, low-energy optimization and software application modifications are supported by Silicon Labs’ Simplicity Studio development tools, which developers can download free of charge.
The RD-0078-0201 occupancy sensor reference design is priced at $49, and the RD-0051-0201 smart outlet reference design is priced at $119. For more information, visit http://www.silabs.com/connectedhome
