2.7G 5.8G microwave induction module bulb lamp ceiling lamp radar induction application
product description
This product uses Doppler radar technology, a microwave sensor module that specifically detects the movement of objects. The 2.7 G microwave signal is used to detect the human body reflected wave, and the lighting circuit is controlled by the circuit processing. The module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle and wide supply voltage range. Widely used in various human body induction lighting and anti-theft alarm and other occasions. Microwave induction is also known as radar induction. The microwave induction switch is an active sensor. The sensor emits high-frequency electromagnetic waves and receives their echoes. This sensor detects changes in the echo, even small movements within the detection range, and then triggers the command . The microwave induction switch is a new type of dead angle-free induction. Based on the principle of Doppler radar, its planar antenna emits extremely low-power electromagnetic waves and receives reflected echoes. It can effectively suppress the interference of high-order harmonics and other clutter. It is a new type of practical energy-saving product with high sensitivity, strong reliability, safety and convenience, and intelligent energy saving. If the reflection frequency of the sensing area is changed, the sensor triggers the action, and the output signal turns
