LinknLink's eMotion Max Is a Compact 60GHz mmWave Radar for Person Sensing and More
Offering a privacy-friendly way to detect and track the occupants of a room, the new sensor offers an upgrade over the original eMotion.
Internet of Things (IoT) specialist LinknLink has launched a crowdfunding campaign for a 60GHz mmWave radar-based human presence sensor that, it claims, delivers high precision with robust protections against interference: the eMotion Max.
"The eMotion Max radar sensor significantly outperforms traditional PIR [passive] infrared motion sensors with its ability to monitor up to 40 square meters (430 square feet) with a single device," LinknLink's Yao Bo claims of the company's latest design.
"It eliminates the need for multiple sensors and their cumbersome configuration," Bo continues, "achieving the equivalent efficiency of multiple integrated PIR sensors by freely setting up to four detection zones (e.g., sofa, bed, or desktop) within 100 grids, enabling personalized automation settings for each zone."
The eMotion Max is based on a 2×2 60GHz mmWave radar, an upgrade over the company's earlier 5.8GHz-based eMotion sensor, and connects to a network through an integrated 2.4GHz Wi-Fi 4 module. The radar portion has a ±60° detection angle horizontally and vertically with a 95 per cent accuracy out to its maximum 6m (around 20 feet) range. It's supported by LinknLink's own software out-of-the-box and can integrate with a range of home automation platforms including Home Assistant, Amazon Alexa, Google Home, and Apple HomeKit.
The company is positioning the sensor as suitable for a range of use-cases, from elderly care and home security to home automation through occupancy-based metrics — the latter aided by its ability to to monitor the movements of up to four individuals in its field of view simultaneously.
The eMotion Max is currently funding on Kickstarter, priced at AU$54 for early bird backers; hardware is expected to ship in September this year, the company has confirmed.
