The smart microwave motion sensor is an electronic occupancy detector operating at a high frequency of 5.8GHz, designed for energy efficient lighting control solutions. Its unique ability to penetrate materials such as plastic, glass and thin non-metallic substances makes it a valuable solution for a wide range of applications. With the mature of microwave radar technology, microwave motion detector gradually replace PIR motion sensor in smart building management & smart cities.
LITWHEAT YW101 is a universal ON/OFF microwave motion sensor switch, which is widely used in applications such as automatic lighting control, security alarm systems and energy management systems.
This microwave sensor motion detector supplies a simple energy saving solution to use light only when and where you need it. It automatically switches on/off light based on motion and ambient light level. Can control all kinds of lamps, for example, halogen, fluorescent and LED lights. Compact size and small casing make it easy to install within most light fixtures. The 5-pole press-in terminal(L,N,P, N’,L’) offers a more organized and flexible wiring diagram.
The high quality relay is particularly suitable for commercial use with switching power up to 1200w@220VAC for LED lighting. Additionally, it offers the option for master-slave group control.

Intelligent Lighting Management
A. Master/Slave Group Control ( Corridor Function)
Master/Slave Group Control is allows for efficient and simultaneous lighting control of multiple lighting fixtures or devices. This arduino radar technology enhances automation and energy efficiency in various settings, such as commercial buildings etc. In this system, one sensor is designated as the “Master sensors,” which serves as the central controller for the group, while the other sensors are “Slave sensors” that follow the commands and settings of the Master sensors, ensuring uniform lighting behavior across the entire controlled area.
B. RF Wireless Mesh Control (Swarm Intelligence)
In a Swarm Intelligent LED lighting system, individual microwave motion sensor light switchs form a RF wireless network, operating in unison to collectively achieve superior lighting performance. This innovative approach allows for adaptive lighting control based on real-time occupancy and movement patterns. The sensors communicate and collaborate to determine the optimal lighting conditions, ensuring that illumination is precisely tailored to the environment’s needs. As a result, energy consumption is minimized, and lighting is only activated when and where it is required.
It’s commonly used in underground parking lots and smart building offices.
C. DALI Lighting Control
DALI (Digital Addressable Lighting Interface) lighting control, when combined with microwave occupancy sensors in LED lighting systems, offers a sophisticated and adaptable solution that revolutionizes the way we manage and control luminaires. DALI is a standardized protocol that provides precise control over individual lighting fixtures or groups of fixtures. Currently, our YW101 doppler radar motion sensor has been updated to DALI-2 version.
DALI allows for granular control of lighting, enabling each fixture to be individually addressed and adjusted. When motion is detected by the microwave presence detector, it can send signals through the DALI network to dim, brighten, or turn on/off specific lights in response to changing occupancy or ambient light levels. This level of control optimizes energy efficiency and can provide tailored lighting experiences. Furthermore, DALI lighting control can be integrated with other building management systems, including HVAC and security.
D. Daylight Harvesting (Constant Lux)
Daylight harvesting is an innovative approach to leverages the availability of natural daylight to intelligently adjust artificial lighting levels in response to changing ambient light conditions. Microwave doppler sensors are equipped to detect both motion and ambient light levels. When combined with daylight harvesting capabilities, they allow LED lighting systems to adapt in real-time. As natural light from windows or skylights varies throughout the day, the microwave motion detector sensors continuously assess the available daylight. If the microwave doppler motion sensor detects sufficient natural light, it can automatically dim or even turn off the artificial LED lighting to save energy.
E. Bluetooth IOT Wireless Control
Bluetooth Wireless Control is a low consumption way of Internet of Things (IoT). The core function of Bluetooth Mesh Control is to enable users to interact with and manage their LED lighting systems using smartphone app remote control. Through smartlife app, users can adjust lighting scenarios, set schedules, and respond to real-time conditions. When combined with microwave motion sensor radar detectors, these systems become highly adaptive and responsive. Bluetooth IoT Wireless Control allows for seamless integration with smart building systems. In an office environment, this can automatically brighten the lights in a conference room when occupants enter and then dimming them when the room is unoccupied.
F. No Back Detection (180° Detection)
The default setting for doppler radar microwave motion sensors is a 360° Detection Range, although some clients may request a 180° Detection Range. This high frequency microwave technology is designed to prevent unnecessary activation of lighting due to motion detected from the rear of the sensor. For instance, in scenarios like wall-mounted luminaires in the hallways or corridors,false activations can occur when motion is sensed from the sensor’s rear, leading to unwanted illumination, especially in spaces where this isn’t desired. No Back Detection in microwave motion sensors addresses this issue by focusing on motion detection primarily in the intended direction, which is the area in front of the microwave doppler radar motion sensor.
G. Absence Presence Detection ( Vacancy Sensing Detection)
In UVC disinfection, safety is paramount, as direct exposure to UVC radiation can be harmful. Absence Presence Detection is designed to ensure that UVC lights are operational only when the area is unoccupied. When ultrasonic motion sensors detect the presence of individuals, they promptly deactivate or dim the UVC lights to prevent any potential exposure to harmful UVC radiation. This guarantees the safety of occupants within the space. The integration of Vacancy Sensing Detection with microwave motion detectors in UVC lighting is particularly valuable inenhancing public health and hygiene in the epidemic outbreaks.
H. Dry Contact Connection
I. Human Presence Detector Technology
Human Presence Detector Technology is an advanced intelligent microwave sensing technology, which adopts 24Ghz mmwave microwave radar technology and utilizes doppler principle to sensitively detect the human body status and static presence. It can automatically activate the lights based on the detection from the human breathing and heartbeat. No matter if the person sits/stand statically in the classrooms, offices, healthcare and other indoor applications, the sensor can accurately recognize its presence and keeps the lights on all the time.
