Silicon Labs has launched two new home automation reference designs including all hardware, firmware and software tools to help home automation developers accelerate time to market and reduce system cost.
FCC and UL pre-certified wireless occupancy sensor and smart outlet designs are based on Silicon Labs’ robust ZigBee “Golden Unit” Home Automation (HA 1.2) software stack and multiprotocol Wireless Gecko system-on-chip (SoC).
“Successful home and building automation products must be standards-based, cost-effective, easy to deploy by end users, and designed to work in real-world environments and solve specific problems with minimal design complexity,” said Daniel Cooley, Senior Vice President and General Manager of Silicon Labs’ IoT products. “We’re helping connected home developers achieve these market-critical objections with pre-certified reference designs based on our breakthrough multiprotocol wireless and sensing technologies.”
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 from Silicon Labs.
Applications of Occupancy sensors are residential and commercial security systems, as well as other home/building automation systems that use occupancy detection to automate tasks such as turning lights off and on. “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”, stated the firm.
The smart outlet reference design is a wirelessly controlled outlet plug that can be used to power and control a wide range of home and building automation products. Powered by an ac main-voltage line, the smart outlet communicates wirelessly to ZigBee mesh networks.
The smart outlet design includes the following features:
- 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 leverage the Silicon Labs’ EFR32MG Mighty Gecko SoC, which provides multiprotocol wireless connectivity for home and building automation. The SoC is based on ARM Cortex-M4 processor with a 2.4 GHz transceiver featuring an integrated power amplifier and balun and capable of +19.5 dBm output power for exceptional low-power wireless range.
Mighty Gecko SoCs run Silicon Labs’ robust Golden Unit ZigBee PRO-certified software stack and ZigBee HA 1.2-certified applications, enabling connected devices to reliably join, interoperate and leave a mesh network, as well as scale from a few to hundreds of nodes on the same network without costly rewiring of existing systems, notes the firm.
The reference designs require Silicon Labs’ ZigBee gateway or an HA 1.2-compliant gateway. Developers can leverage silicon Labs’ Simplicity Studio development tools for system configuration, debugging, low-energy optimization and software application modifications.
Silicon Labs’ occupancy sensor and smart outlet reference designs, including complete schematics, layout and bill of materials (BOM), are available today. 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. (All prices USD MSRP.)
