Microwave motion sensors have emerged as pivotal components, especially in motion detection technology. LITWHEAT, a leading manufacturer of energy efficient lighting controls, introduces DALI Lighting Controls, Zhaga D4i Motion Sensor, Bluetooth Motion Sensor, Highbay Dimming Sensor etc.
Among the various options available, ON/OFF HF motion sensors stand out as a popular choice for Original Equipment Manufacturers (OEMs), including relay and triac versions. The YW101 microwave motion sensor and YW102 HF motion detector have more the same features and differences.
I Key Features of YW101 and YW102:
1. 5.8Ghz C-band microwave motion sensor, on off control.
The YW101 and YW102 microwave movement detectors both incorporate a YW002 doppler radar chip, combining a high-performance 5.8Ghz microwave radar PLL oscillator, which enhances frequency stability, reduces faulse alarms and filters out interference through sophisticated algorithms. Besides this, the microwave presence detectors boast long-distance coverage and high sensitivity, unaffected by ambient temperature changes.
2. Zero Crossing Protection.
To ensure the longevity of the microwave motion detectors and protect against high inrush current from LED drivers, the YW101 and YW102 microwave movement sensors come equipped with zero voltage switching. This feature enhances the overall durability and performance of the microwave occupancy sensors.
3. Convenient Parameter Adjustment.
All parameters of these microwave radar motion sensors are conveniently adjusted via external DIP switch controls and the complete products are sealed with the same housing. This design eliminates the need to open the motion detection sensor during setting operations and secure installation. It is not only widely used in human body detection for energy saving lighting, but also in other applications, like security, building automation, UVC disinfection etc.
4. Smart Controls & Connectivity
Additionally, these HF motion detectors can seamlessly integrate with other smart lighting control systems, allowing for further optimization of energy usage based on occupancy patterns and monitoring capabilities.

5. Advancements in Energy Efficiency
Arduino microwave motion sensors offer a compelling solution for energy conservation by intelligently responding to human presence or movement within a defined space. Unlike traditional lighting systems that remain constantly illuminated, regardless of occupancy, microwave doppler motion sensors actively detect motion and trigger lights to turn on only when needed. This responsive behavior eliminates unnecessary energy consumption during periods of inactivity, leading to subst antial energy savings.
II Distinguishing Features:
1. Dimensions:
YW102— H20mm/H25mm x L64mm x W38.5mm; YW101— H25mm x L64mm x W38.5mm.
The YW102 arduino microwave radar sensor features dimensions of H20mm/H25mm x L64mm x W38.5mm, providing flexibility in height options. On the other hand, the YW101 has slightly larger dimensions with a fixed height of H25mm x L64mm x W38.5mm. In situations where height is not a critical factor, the default height of H25mm can be employed for both models.
This height flexibility allows users to choose the most suitable option based on their specific requirements or constraints. Whether opting for the YW102 with a variable height of H20mm or H25mm or the YW101 with a fixed height of H25mm, these dimensions cater to diverse installation scenarios while ensuring the radar motion switches seamlessly integrate into various settings. The flexibility in height options adds versatility to the YW102, offering adaptability to different environments and user preferences.
2. Relay Sound:
YW102 operates without a buzzing relay sound; YW101 operates with a relay sound
When it comes to relay sound, the YW102 doppler radar motion sensor stands out for providing a noise-free experience as it operates without any buzzing relay sound. In contrast, the YW101 emits a relay sound during its operation. This distinction in auditory characteristics can be a crucial factor for users who prioritize a silent and unobtrusive environment. The YW102’s silent operation ensures that its presence goes unnoticed, making it an ideal choice in applications where noise reduction is paramount. On the other hand, the YW101, while effective in its functionality, introduces an audible relay sound during operation, which may be a consideration in settings where minimizing noise is essential for user comfort and satisfaction.
3. Max Load Capacity:
YW102 Max. 400W@200-240VAC; YW101 Max.1200W@200-240VAC
In terms of maximum load capacity, the YW102 microwave daylight motion sensor switch supports a maximum load of 400W at 200-240VAC, meeting the majority of market demands effectively. In contrast, the YW101 surpasses this capacity, accommodating a higher load of up to 1200W at 200-240VAC. This distinction becomes significant when there are greater capacity requirements for master/slave control applications. The YW101’s higher load capacity allows it to connect more luminaires, making it the preferred choice in applications where a broader lighting network needs to be controlled.
The enhanced capacity of the YW101 not only caters to larger lighting setups but also provides added flexibility in designing and managing lighting systems. Whether in commercial spaces or expansive residential areas, the YW101’s higher load capacity ensures efficient and versatile control over a multitude of luminaires, meeting the demands of diverse lighting requirements.
