📌5.8GHz Microwave Radar Sensor Module BM22S4421-1
💻More Information: [ Ссылка ]
✒Description
The product is a microwave radar module that transmits electromagnetic wave at frequency band of 5.8GHz. It operates based on the Doppler effect, detecting variations between the transmitted and reflected waves to determine whether a moving object is within the detection area.
It is suitable for applications of motion sensor lights, smart home, security, etc.
▓Differences between microwave radar modules and PIR modules
Both microwave radar modules and PIR modules can be used to detect motions of objects, although their operations are different.
Microwave radar modules have higher sensitivity than PIR modules and are not affected by ambient light. However, they mistrigger more easily than PIR modules.
▓The detection angle and distance
The maximum detection distance of the product can range from 5 to 14 meters and can be configured across 7 levels.
The detection angle is 360°. The side of the product with the Best Modules logo is considered the front side. When installing, position the side with the logo facing towards the area to be detected.
For example, when installing on the ceiling, the side with the logo should face towards the ground.
