Description

In both directions to detect motion detection sensor

The present invention can reduce the initial installation cost by reducing the number of installation of the sensor module to be installed by detecting the front and rear direction at the same time in the form of the microwave motion sensor facing the front and rear side, and the operation within the detection range The present invention relates to a two-way sensor for motion detection that can reduce costs by turning on and off the lights only when it is detected and reducing the use of lights in unnecessary areas or time zones, and using energy saving and long-life lighting.

In general, a sensor or a sensing device detects or detects various types of physical quantities such as temperature or pressure, and transfers the detected information to a means corresponding to the information processing unit to make an appropriate judgment and to operate the device accordingly. It acts as a collector.

The physical quantity to be detected by the sensor may be a variety of types, such as magnetic, displacement, vibration, acceleration rotational flow rate or flow rate, liquid component, gas component, visible light, infrared, ultrasonic wave, microwave radiation, X-ray, output signal Furnace uses amplification and storage in memory, or remote control is simple, electrical signal is mainly used due to ease of handling when input.

Such sensors include light sensors, ultrasonic sensors, and microwave motion sensors.

Among the sensors, the microwave motion sensor device applies the Doppler radar principle to transmit microwave waves through the transmitting antenna to receive the radio wave reflected by the sensing object as the receiving antenna and detect the motion.

The motion detection sensor detects the distance from the object approaching the nearby area by detecting the motion by detecting the motion and detects the minute movement of the object by the person or the object within the range detected by the sensor. Energy is efficiently used while lighting or extinction is controlled in a place, and at a predetermined predetermined lighting time that a vehicle or a person frequently enters or exits, the lighting is controlled regardless of whether a vehicle or a person is detected.

In the case of the microwave motion sensor based on the existing Doppler radar principle, the detection angle is limited to 120 ° ~ 130 °, so it can detect only moving objects within the detection range in one direction. At least two sensor modules were needed at a point in the case where sensing is required.
