What is a microwave sensor

What is a microwave sensor

Radar sensor, also known as microwave sensor, is based on the Doppler effect and adopts the most advanced planar antenna, which can effectively suppress the interference of high-order harmonics and other clutter, with high sensitivity, high reliability, safety and convenience. Intelligent energy saving is the first choice for building intelligentization and property management modernization. Micro power consumption, complete functions, can match all kinds of access control switches.

Functions and Features

1. Intelligent induction: When someone enters the detection range of this product, the microwave detector works to open the access control

2. Intelligent delay: The switch will automatically delay a cycle after detecting each movement of the human body, and the delay time of the last human movement will be the starting point.

3. Working method: After the induction switch is turned on, within the delay time period, if there is human activity, the switch will continue to be turned on until the person leaves and the time is extended.

4. Photosensitive control: according to the light intensity of the outside world, to control whether the switch works, in order to achieve the effect of energy saving.

5. Compared with infrared products: radar sensing distance is longer, wide angle, no dead zone, can penetrate glass, and thin wood, according to different power, can penetrate walls of different thicknesses, not affected by environment, temperature, dust, etc. , in the case of 37 degrees, the sensing distance will not be shortened.

 Microwave radar sensing characteristics

The reason why microwave is widely used is mainly to make full use of the three characteristics of light likeness, penetrability and long sensing distance.

Photolikeness: refers to its ability to propagate anchors and concentrate more like light rays than radio waves with lower frequencies;

● Penetration: Compared with infrared rays, it is easier to penetrate into the material when irradiating the medium.

●Induction distance: up to 8-18 meters.

什么是微波传感器

雷达传感器又称微波传感器，基于多普勒效应，采用最先进的平面天线，可有效抑制高次谐波等杂波的干扰，具有灵敏度高、可靠性高、安全方便等特点。智能节能是楼宇智能化和物业管理现代化的首选。微功耗，功能齐全，可匹配各类门禁开关。

功能和特点

1、智能感应：当有人进入本产品探测范围时，微波探测器工作，开启门禁

2、智能延时：开关检测到人体的每一次动作后，会自动延时一个周期，以最后一次人体动作的延时时间为起点。

3、工作方法：感应开关打开后，在延时时间内，如果有人活动，开关会继续打开，直到人离开，时间延长。

4、光敏控制：根据外界光照强度，控制开关是否工作，以达到节能的效果。

5.与红外产品相比：雷达感应距离更长，广角，无死区，可穿透玻璃，薄木，根据功率不同，可穿透不同厚度的墙壁，不受环境、温度、灰尘等影响. ，在37度的情况下，感应距离不会缩短。

微波雷达传感特性

微波之所以被广泛使用，主要是为了充分利用光似、穿透性和感应距离远这三个特点。

光相似性：是指其传播锚点的能力，它更像是光线而不是频率较低的无线电波；

● 穿透性：与红外线相比，照射介质时更容易穿透材料。

●感应距离：可达8-18米。
