Human Body Microwave Sensor Radar Human Presence Sensing Intelligent Lighting Control

Human body microwave sensor radar human body presence sensing intelligent lighting control, in recent years, the rate of myopia among young people has increased year by year. According to the survey, about 80% of students suffer from myopia if the lighting conditions of homes or schools do not meet the standards for lighting eyes. With the development of science and technology, smart products have penetrated into all areas of our lives, and lamps and lanterns have become a necessity for thousands of households. Smart lights provide users with a suitable and comfortable lighting environment while protecting eyesight and promoting a good living and learning environment.

In low-light situations, smart lights can appropriately supplement light for people. With the improvement of the degree of intelligence, the functions of table lamps are not only satisfied with ordinary lighting. Portable multi-function lamps, intelligent radar human body induction light. It includes a humanized design, which is convenient for the light of the lamp head to be scattered downward by 45°, effectively avoiding the damage of direct light to the eyes. In order to achieve a suitable working and learning lighting environment, the PWM stepless adjustment method is used to adjust the brightness and color temperature of the LED lights.

Human body microwave sensor radar is a sensor that uses electromagnetic waves to detect the target, from the target to the electromagnetic wave emission point, the distance, distance change rate (radial velocity), direction, angle and other information, through the emission of electromagnetic waves to illuminate the target and receive echoes. The human body microwave sensor contains an ultra-low power consumption 5.8ghz radar module. It adopts an ultra-low power consumption system. The integrated signal processor inside the chip can directly output the induction control signal. The external combination with a small number of components forms a complete microwave induction sensor. It is an upgrade choice for traditional infrared heat release sensors, which can meet the ultra-low power consumption requirements of battery-powered application scenarios.

The intelligent lighting power circuit is divided into two parts: lithium battery discharge and charging power tube. When using USB power mode, the lithium battery is also charged to the circuit at the same time. When there is no external USB power supply, use the lithium battery power supply. The human body microwave sensor can control the light to automatically turn off when people walk, and automatically turn on when there are people, saving electricity, and the human body microwave sensor can detect whether there is someone in front of the light.

In order to meet the power consumption of battery power supply, within the radar detection range, the light is turned on when people come and the light is off when people leave, and the power consumption is as low as 40uA.

The radar human body microwave sensor can determine whether there is anyone around the light. If there is no one, after starting the timer for 5s, if there is still no one around, the light will be automatically turned off, but if someone is found, the light will continue to be turned on, and the previous brightness and color temperature.

When winter comes, the night comes faster. On the one hand, the weather is getting colder. A dark room feels cooler when you get home from get off work. The lights outside the window were dim, and the lights in the room were dim. In low light conditions, the smart sensor light will turn on together with the human body microwave sensor radar sensor. When you get close to the radar sensing area of the light fixture, it will automatically turn on the light fixture for easy passage. When you leave the sensing area for 15 seconds, it will automatically turn off. Smart sensing technology can make us feel warm and comfortable when we come home.

Intelligent radar sensing can sense your presence precisely, and intelligent lighting, because it has built-in radar human sensor, can sense the human body within a range of 120° within a range of 4-10 meters. Lights where you need it (stairs, cabinets, bathrooms and bedrooms) without drilling and screws.
