Microwave motion sensor is an active motion sensor that emits high-frequency waves (5.8GHz±75MHz).
Microwave sensor, also known as radar sensor,works on the principle of the Doppler effect. The sensor emits a signal and receives its echo. If a movement in the dectection zone changes the echo pattern, the sensor responds and switches the light on.
1. microwave sensors using planar antenna and receiving echo. 2. The switch is active sensors. 3. The sensors emit a high-frequency electromagnetic waves and receives their echo. 4. The sensors detect changes in the echo program. 5. The sensors detect tiny movements in detecting range. 6. Send the signal to the MCU and execution of instructions. 7. The signals are likely to be detected through the door glass and thin-walled. 8. It will get better result if the person or object when moving toward the sensor probe. 9. This product is a strong anti-jamming, almost no wind, heat and other environmental factors foreign interference
10. High sensitivity & energy efficient, No UV and IR radiation, No flicker.
Twinlinkis a professional manufacturer for microwave motion sensor and smart lighting control with more than 10 years experience in Shenzhen ,China .

Why choose Twinlink's Microwave Motion Sensor?
Touch control or panel control requires human touch, it might be invalid in winter waring gloves and extremely inconvenient in night.
Sound control induction is most easily affected by the ambient environment disturbance, not suitable for noisy places.
The principle of the PIR is sensor detects human body temperature and compares with sensor’s characteristic temperature to control light. But Infrared sensor has small detection angle and short detection distance; less sensitivity when ambient temperature changes.
Microwave motion sensorhas advantages as: long detection distance, strong interference ability, high sensitivity; different detection range, holdtime, daylight threshold, standby dimming level and standby period settings for different applications.
