The microwave technology can precisely detect human breath when they are in stationary positions in the targeted area, and trigger different dim levels according to detected human movements, realizing more humanized management of lighting. IoT-based motion sensor supports switching on/off, two dim levels, three dim levels and four control modes, which nicely works with traditional load lamps and satisfies different users’ demands. The product it is DALI, 0-10V protocol compatible, which can cover all residential and office lamp applications. With the feature of sensing natural and artificial light, it can automatically turn off lamps when the natural light is sufficient to save your energy. Through the APP and a visual remote, users can remotely set up parameters so a comfortable and energy-saving environment can be easily created. Compared to traditional infrared sensor, this IoT-based sensor has a lot of benefits, from reducing installation time to easing the complexity of operation. With the outstanding energy-saving advantage, it saves electricity costs for customers and eases the environmental burdens, making contributions to protecting the environment. At the same time, the sensor can collect the user's human body data, and deliver a better user experience based on the big data algorithm.
