Feedback Stabilizing Magnetic sensor in CARDET

Unlike conventional magnetic sensor such as a 3‐axis magnetic compass module, CARDET has the unique technology of FEEDBACK STABILIZING magnetic sensing properties, so it shows the ultra stable characteristics of sensing performance for the vehicle detection. CARDET shows the whole different superior performance and stability compared than the conventional magnetic sensor.

All the magnetic material has a special effect named as Barkhausen effect that makes randomly high peaks in the magnetic domain inside the material, this noise is the main cause of the mis-operation of magnetic sensor, which makes false-alarms many times per a day, but Feedback Stabilizing magnetic sensor by MAGO technology has a  special structure that cancel out the Barkhausen noise fundamentally, so CARDET series has no false alarm by the Barkhausen noise.

레이더 감지 기술은 기본기술인 전파의 송수신, 신호처리기술도 중요하지만 특히 전파의 방사 및 집진기술이 매우 중요합니다. 마고테크놀러지는 레이더 전파의 방사 및 집진 기술 많은 연구를 거듭하여 차량 감지에 최적화된 레이더 전파 송수신 집진 시스템의 개발에 성공하였습니다(특허출원.)

레이더 센서는 날씨 및 온도에 크게 구애 받지 않으며, 특별한 구조에서는 초 저전력 동작이 가능하여 배터리를 내장한 센서에도 적합합니다. 마고 테크놀러지의 CARDET-501, 주차면센서, 열차센서등에 사용된 RADAR 감지기술은 차량감지에 국내 최고로 최적화된 센서기술 입니다.

Digital Integral Proximity sensor in CARDET

The digital ultrasonic sensor inside CARDET‐301 is not a conventional analog ultrasonic sensor, it has its own DSP and effective digital algorithms for stable performance on any conditions. MAGO technology developed the special digital Integral measurement method for the proximity sensor to detect vehicles on the road without mis-operation, and we have the edge technology of filtering out various noises on the road.

​The digital ultrasonic(DU) proximity sensor by MAGO has a special digital signal processing  function such as a movie camera. The sensor executes many of sensing frames such as a optical vision sensor, this special structure(time-warp) has the superior performance to extract the exact feature from noisy environment. Only DU proximity sensor by MAGO has this unique function in this cost effective proximity sensor for detecting vehicles.

Car detection sensor CARDET

All of the signal processing algorithm inside CARDET‐301 was optimized for the characteristics of the target object, and the digital integral measurement algorithm guarantees stable outputs under various noises on the road. 

​After version 4.0, Digital Ultrasonic sensor embeds the AI function of automatically recognize the environment of the area of sensor installed.

Organic configuration using both of magnetic and integral proximity sensors

CARDET has the organic structure using both of FS MAGNETIC and DI PROXIMITY sensors, it has not affected by an human, animal, snow or rain. It does not need expensive ground constructions, and has an extremely long life time. CARDET is NOT damaged by heavy trucks in summer, and also by snow plows in winter.

CARDET is the best magnetic based vehicle detecting sensor

Car detection sensor CARDET

MAGO technology has the world best technology for precision magnetic sensor, we also developed and produce the micro MAD sensor(ultra precise military magnetic sensor) for military purposes. CARDET is the consumer product that was applied of the military technology of the stable measurement. It has an adaptive digital filter for tracking the change of Earth magnetic field.

CARDET the vehicle detection sensor is a stable and reliable sensor that has obtained KC certification. CARDET(Excluding user negligence and natural disasters)

CARDET the vehicle detection sensor can distinguish a vehicle even in a situation where pedestrians and vehicles are mixed, so when used in conjunction with existing sensors, it can significantly reduce the frequency of errors or errors in the system, and dramatically improve the safety of pedestrians and vehicles. It is possible. 

We have the tools and technology to design the optimization work on site and on the same day when the sensors are used in parallel.


CARDET-101  Omni-directional vehicle detecting sensor

Car detection sensor CARDET

[ Detection area of CARDET-101 ]

CARDET-101 has an omni-directional sensing area(a sphere shape), it detects the vehicle that passing by near the sensor with all direction. Detection distance is 1.8 meters for a full sized sedan(movement detection). CARDET-101 can cover 2 traffic lanes with one sensor.

car detection sensor CARDET

CARDET-101 is the best for controlling an automatic door, alarming light, antiseptic dispensor(disinfecting work), etc. CARDET has a variety of accessaries including CONTROL BOARD that can be embedded of several customized logics.

CARDET-301  Uni-directional vehicle detecting sensor

Car detection sensor CARDET

CARDET-301 has an uni-directional sensing characteristic, it detects only the vehicle in front of the sensor. Detection distance is also 1.8 meters for a full sized sedan, detection angle is ± 30 degree. CARDET-301 has the capability of making precise trigger signals for the connected device, so it is suitable for controlling a toll bar, counting vehicles, LPR system, etc.


​CARDET-301 is the unique sensor that has an uni-directional detection characteristic among the magnetic based sensor for vehicle in the world.

There are a plenty of noise that always varies on the road,  so the most important charateristic for the magnetic based vehicle sensor is to retain the detection area againt the noises. CARDET has the special kind of design structure of keeping the detection area stable using the FEEDBACK STABILIZING technology. CARDET shows the outstanding performance with the highest stability.

CARDET-201 Parking sensor for the parallel parking place


CARDET-201 was developed for the use of the parallel parking place. It is installed under the surface of the ground as the left figure.

CARDET-201 has the FS magnetic sensor, special digital filters and optimized detection algorithm inside, and it also has the special algorithms for the long time parking and around cars passing by. 

Users can build up the unmanned parking control system very easily with this sensor.

CARDET-CP-IoT Battery type buried parking sensor


The CARDET-CP-IoT model is a battery operated, convenient parking surface sensor capable of wireless communication with advanced radar. All hardware is built into a single sensor module, so there is no need for a separate receiver, and all construction work is completed by installing the sensor module.

SBS (Sensor Bridge System) automatically performs battery management and communication efficiency management of the sensor, and the user only needs to access the Internet and read the status value without separate management.

Since SBS automatically performs sensor management, server development at the back end is extremely simplified even without expert knowledge about sensors, and the server work of the parking control system is completed with only MMI development.
