Proven Professional mmWave Presence Sensor Supplier

As a truly innovative smart home solution provider, LinknLink has taken a different path from day one. Unlike traditional smart home companies, we focus exclusively on two core product categories: smart gateways and presence sensors.

From the very beginning, we moved away from conventional PIR technology. Over the past three years, we have successfully developed multiple generations of our eMotion product line — starting with the first-generation 5.8 GHz eMotion, followed by the 24 GHz eMotion Pro, and advancing to our high-end 60 GHz eMotion Max and eMotion Ultra. These products have received broad recognition and positive feedback from the market.

The technology and expertise we have accumulated in mmWave presence sensing are proven, reliable, and truly differentiated. You can trust not only our technical foundation, but also the strong validation from real-world users and numerous smart home influencers who have reviewed and recommended our products.
