Microwave Sensor Switch，5.8GHz radar module(OEM/ODM)
Microwave sensor switch adopts professional 5.8GHz radar module, through the high gain low side-valve planar microstrip antenna, transmits fixed frequency 5.8GHz±75Mhz CW radio waves to the sensing area, and receives all the reflected radio waves in the area, which are converted into differential frequency electrical signals by mixing circuits in the module; according to the principle of Doppler effect, it is processed by high-performance digital signal recognition algorithms, and analyzes whether there is any motion target in the area or not, thus controlling the load power switch. According to the principle of Doppler effect, through high-performance digital signal recognition algorithm processing, analyze whether there is a moving target in the area, so as to control the load power switch.
RA5K01 microwave sensor switch can be widely used in lighting, security, smart home, home appliances, IoT devices and other products that need to detect human movement, adding intelligent sensing function for the device, bringing users an excellent sensory experience.

Product Applications
Products are mainly used for lighting, security, home, home appliances, bathrooms, hotels, garages, buildings, transportation, IoT Internet of Things, and need to detect the industry’s field of micro-motion and movement.
Precautions
1. Emperor radiation:
The front of the radar switching antenna should avoid metal objects (containing shells), and can have plastic, glass, wooden boards, and other penetrated obstacles. In addition, the larger the horizon provided to the radar switch, the less radiating it is, and more energy will radiate from the front of the antenna.
2. Other sports object interference:
Try to avoid moving/shaking objects such as large metal equipment, ventilation pipelines, fire pipelines, and drainage pipelines in large blocks. Because their movement Doppler frequency falls into the movement frequency of the personnel, causing misunderstandings. Some customized versions can solve the problem of fixed interference sources (such as electric fans, air conditioners, bathing, etc.).
3. Multi -switching installation:
When installation of multiple radar switches, the antennas of each radar switch should be parallel to each other, irradiation or in the opposite direction, to avoid each switch from each other, and the switch and the switch are kept by 1M or more.
4. Work frequency and harmonic interference:
The radar switch has made a variety of industrial frequency interference and multiple harmonic suppression algorithms. However, it is still recommended to stay away from circuits such as high -voltage AC power supply, rectification bridge, high -power electrical drive, etc., and design the design of voltage voltage, shielding, and power integrity, so as not to super strong industrial frequency interference, exceed the range of switching inhibitory capacity, and cause errors.
5. Light interference:
The light -emitting changes of the luminous component may cause the light intensity detected by the light sensing device to change too much, causing the switch to continue to switch between the shutdown detection and opening the detection function, and the control signal is abnormal. It is recommended that during the installation process, the light sensing device on the radar switch should be avoided directly or indirectly by the light emitted by the luminous component. This version of the radar switch uses a single light sensor to detect ambient light. Natural light detection sensors and multi -light sensor combinations can be used to avoid this problem.
6. Strong penetration:
Compared with 24GHz, 60GHz, 77GHz millimeter waves, 5.8GHz microwaves have stronger penetration capabilities. They can penetrate thin wooden boards, ceramics, glass, and plastic, but generally it is not easy to penetrate the brick wall.
7. Pay attention to ESD protection:
Do not touch the antenna and circuit with your hands, so as not to cause excessive human body to contact discharge and damage the radar switch.
