* Feedback Stabilizing Magnetic sensor in CARDET

Unlike conventional magnetic sensors such as a 3-axis magnetic compass module,CARDEThas theunique technology of FEEDBACK STABILIZING magnetic sensing properties,so it shows the ultra stable characteristics of sensing performance for the vehicle detection.CARDETshows the whole different superior performance and stability compared than the conventional magnetic sensor._cc781905-5cde-3194-bb3b -136bad5cf58d_

All the magnetic material has a special effect named asBarkhausen effectthat makes randomlyhigh peaksin 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, butFeedback Stabilizingmagnetic sensor byMAGO technologyhas a  special structure that cancel out theBarkhausen noise fundamentally, soCARDETseries has no false alarm by the Barkhausen noise.    

* Digital Integral Proximity sensor in CARDET

Thedigital ultrasonic sensor insideCARDET-301is not a conventional analog ultrasonic sensor, it has its ownDSPand effective digital algorithms for stable performance on any conditions.MAGO technologydeveloped thespecial 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.

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

All of thesignal processing algorithminsideCARDET‐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 sensorembeds theAI functionof automatically recognize the environment of the area of sensor installed.


* Organic configuration using both of magnetic and integral proximity sensors

CARDEThas the organic structure using both ofFS MAGNETICandDI PROXIMITY sensors, it hasnot affected by an human, animal, snow or rain. It does not need expensive ground constructions, and has an extremely long life time.CARDETisNOTDamaged by heavy trucks in summer, and also by snow plows in winter.

CARDET is the best magnetic based vehicle detecting sensor

MAGO technologyhas the world best technology for precision magnetic sensor, we also developed and produce the microMADsensor (ultra precise military magnetic sensor) for military purposes.CARDETis 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-101  Omni-directional vehicle detecting sensor

[ Detection area of CARDET-101 ]

CARDET-101has an omni-directional sensing area (a sphere shape), it detects the vehicle that passing by near the sensor with all direction. Detection distance is1.8 meters for a full sized sedan (movement detection).CARDET-101can cover 2 traffic lanesit one sensor.

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

CARDET-301  Uni-directional vehicle detecting sensor

CARDET-301has an uni-directional sensing characteristic, it detects only the vehiclein front ofthe sensor. Detection distance is also1.8 metersFor a full sized sedan, the detection angle is ± 30 degree.CARDET-301has 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 sensor1905 -3194-bb3b-136bad5cf58d_retain the detection area againt the noises.CARDEThas the special kind of design structure ofkeeping the detection area stableusing theFEEDBACK STABILIZING technology.CARDETshows the outstanding performance with the highest stability.

CARDET-201  parking sensor for the parallel parking place

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

CARDET-201has theFS magnetic sensor,special digital filtersandoptimized detection algorithminside, 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-PR  multi-purpose intelligent vehicle sensor

CARDET-PRhave theDIGITAL INTEGRAL proximity sensorthat was developed byMAGOtechnology.DI Proximity sensor has the digital Integral measurement structure ofextracting the exact signals of the target from the noisy signals.

This smart sensor hasits own DSPfor the digital measurement method, and also several digital filters to get rid off noises from the environment.

CARDET-PR can be used for various purposes, one of the application is detecting vehicles at the parking place as the right figure.
