FEATURES OF THE MICROWAVE SENSOR SWITCH
- RS02D2 is a 5.8GHz radar microwave sensor switch. It detects body waves from people or objects with motion frequencies sensitive to this frequency range. When movement is detected within the sensing area, it sends a signal to the switch relay to turn on the light. It is not affected by ambient temperatures above 32°C and can detect through wooden partitions, glass, thin walls, plasterboard, and more.
- Automatically turns on the light when someone moves within the detection area. The SENS distance adjustment function allows the sensing range to be adjusted as needed, making it suitable for different spaces.
- Combined with the adjustable LUX function for ambient brightness. If the surrounding light is bright enough, the light will not turn on, helping save electricity.
- Switch Microwave Sensor RS02D2 features continuous motion detection. Therefore, the light-on time is maintained for the preset duration. When no further movement is detected, the device will switch off the light.

DIFFERENCES BETWEEN MICROWAVE SENSOR SWITCHES AND INFRARED SENSOR SWITCHES
| Comparison Criteria | Microwave Sensor | Infrared Sensor |
|---|---|---|
| Operating principle | Uses radar waves to detect body waves from humans or animals with wave frequencies similar to the human body. | Uses infrared rays to detect moving body heat; the body temperature should be around 36–37°C. |
| Sensing angle and radius | Scanning angle: 160°–180°; radius: 2–6m, adjustable. | canning angle: 110°–145°; radius: 2–4m at >29°–32°C, 4–6m at 24°–28°C. |
| Advantages | Wide angle, long sensing distance, and adjustable sensing range. Can detect through plastic, wood, glass, and plasterboard partitions. RS02D2 can be installed inside a lamp or recessed into a plasterboard ceiling. | The sensing angle can be limited by covering part of the sensor lens with tape. Suitable for small and narrow areas. The sensing direction can be adjusted by rotating the sensor toward the desired detection area. |
| Disadvantages | The sensing angle cannot be limited. | Narrower sensing angle and non-adjustable sensing distance. Sensitivity and sensing distance depend on ambient temperature and the movement direction of the heat source. |
| Installation position | Can be installed inside a lamp cover or mounted separately outside. | Can only be mounted separately outside, and the sensor lens must be exposed. |
BENEFITS WHEN USING MOTION SENSOR SWITCHES
- Helps reduce the risk of electric shock and bacterial contamination. This is especially useful for children and elderly people who often need to touch traditional electrical switches directly when using the toilet.
- Saves electricity by preventing lights from being left on after people leave, especially in families with children and elderly members.
- Saves time by reducing the need to walk over to turn lights and other devices on/off manually.
- Helps improve home security, because when someone enters the area, the light will turn on automatically, making it easier for homeowners to detect intruders.
- Can be recessed into lighting fixtures such as ceiling lights, balcony lights, and more, ensuring high aesthetics for your home.
- Not affected by ambient temperatures above 32°C, making the product durable and helping prevent lights from turning on/off at the wrong time.
THE DIFFERENCE BETWEEN KAWASAN MICROWAVE SENSOR DEVICES AND OTHER PRODUCTS ON THE MARKET
- KAWASAN RS02D2 microwave sensor device is researched, improved, and manufactured in Vietnam. It has clear origin certification and meets the demand for microwave sensor devices in the Vietnamese market. It offers high sensitivity, stable performance, and is less affected during use. Especially in hot weather above 32°C, the sensor still operates normally.
- Other microwave sensor switches on the market may have a lower price. However, their quality is often inconsistent, with insufficient load capacity and sensitivity that is not properly adjusted. Sometimes they are too sensitive, causing the light to stay on continuously, or not sensitive enough, causing the light not to turn on when someone enters.
- KAWASAN sensor switches usually have a durability of over 3 years and come with a 2-year warranty. Compared with many products on the market, which usually last about 1 year and have a warranty from 3 months to 1 year, the cheaper price may actually lead to much higher replacement costs over a 3-year period.
HOW IS THE RS02D2 MICROWAVE RADAR SENSOR APPLIED?
Can be added to existing lights to turn them into sensor lights:
For example, stair lights, balcony lights, gate lights, and similar lighting areas are often already equipped with wall lights or ceiling lights. The RS02D2 can be recessed inside the light or installed right next to it, thanks to its compact microwave sensor design and simple wiring connection.
Recessed installation into various tube light fixtures:
RS02D2 can be recessed into 0.6m or 1.2m tube light fixtures, or waterproof light fixtures installed in factories, parking lots, garages, and more. It helps prevent wasted electricity caused by forgetting to turn off the lights and reduces the need to monitor or remind employees.

Recessed installation into lights in public restrooms or home bathrooms with partitions, adding RS02D2 to turn them into sensor lights. For some bathrooms with partitions, a microwave sensor is needed because microwave sensing can penetrate obstacles well.

Attention: In cases where the sensor is recessed into a plasterboard ceiling or installed inside a light fixture, the device body cannot receive outdoor light, so it cannot detect natural light. This means the light will turn on whenever someone enters the area.
