The 5.8g microwave radar security sensor module makes security more intelligent. The radar microwave module has the characteristics of high sensitivity, long sensing distance, strong reliability, large sensing angle, and wide power supply voltage range. Doppler radar technology automatic sensing control products. Widely used in various human body induction lighting, security, anti-theft alarm occasions.
5.8g Microwave Radar Security Sensor Module Features: Microwave induction adopts advanced technology, and a plane antenna is used to transmit and receive microwaves. Microwave sensing uses switches as active sensors that emit high-frequency electromagnetic waves (5.8GHz) and receive their echoes. The sensor detects changes in echoes, even small movements within range, and then triggers and executes commands. The signal goes through the gate. Glass plates and thin walls can be detected, the product has strong anti-interference ability, and is hardly disturbed by external environmental factors such as wind and heat, and the security sensor module will not shorten the sensing distance with the extension of use time. The shortcomings of infrared sensors are well avoided, and a reliable mobile sensor is truly realized.
5.8g microwave radar security sensor module application scenarios: 1. Energy-saving control of lighting in public places; 2. Energy-saving control of home lighting; 3. Security community anti-theft monitoring system; 4. Induction automatic doors; 5. Children's toys.
With the continuous development and progress of various software and hardware technologies related to microwave radar sensor technology, sensor information integration has become a special technology for information induction processing, and is rapidly applied to security industry, robotics, intelligent detection, automatic control, traffic management and medical diagnosis and other fields.
Microwave radar sensors have four distinct characteristics:
1. Information redundancy: For a certain feature of the environment, it can obtain multiple information through multiple sensors (or multiple single sensors at different times). This information is redundant and has varying reliability. After the integration process, more accurate and reliable information can be extracted. In addition, information redundancy can improve the stability of the system and prevent the failure of a single sensor from affecting the entire system.
2. Information complementarity: Different varieties of sensors can provide the system with information of different natures. The objects described by these information are different environmental features, which complement each other. If a coordinate space composed of all features is defined, the information provided by each sensor only belongs to a subspace of the whole space, and is independent of the space formed by other sensors.
3. Timeliness of information processing: The processing process of each sensor is independent of each other. The whole processing process can adopt the parallel heat conduction processing mechanism, which makes the system processing faster and provides more timely processing results.
4. Low cost of information processing: Multiple sensors can cost less to obtain an amount of information equivalent to that obtained by a single sensor. If the information provided by a single sensor is not used for other functions, the cost of a single sensor is comparable to the sum of the costs of multiple sensors.
