Pre-certified reference designs for smart homes
Silicon Labs (Austin, TX) has created pre-certified occupancy sensor and smart outlet designs that employ its multiprotocol Wireless Gecko MCUs and ZigBee Mesh Stack. There are two wireless occupancy sensor and smart outlet reference designs for the home automation market to provide IoT connected devices.

The FCC and UL-pre-certified reference designs include all of the hardware, firmware and software tools required to create 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) range.

The reference designs help home automation device makers and developers reduce system cost and complexity with ZigBee mesh networking technology. Designers can access pre-certified wireless technology, open-source hardware design files and industry-standard software stacks that come with test setups and manufacturing methods.

The occupancy sensor reference design is a pre-certified ZigBee HA 1.2 system featuring a wirelessly connected passive infrared sensor along with ambient light and temperature/relative humidity sensors from Silicon Labs. The occupancy sensor’s small, battery-powered design (the size of two AAA batteries) can operate for up to five years before battery replacement. The sensor’s detection range extends up to 12 metres 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 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; built-in diagnostics and metering with a user-friendly web interface for wireless control and current/voltage monitoring, accessible from mobile devices; wide AC voltage range (110-240 V) for global use along with a 15 A load current; integrated high-accuracy sensors for ambient light and temperature/humidity; and a 6.5 x 6.5 x 4.0 cm outline.
