CARDET Line-up

1. Car detection for a LPR(License Plate Recognition) system

CARDET sensor(301/501/LD) generates an accurate trigger signal for a LPR system to capture the license plate of the coming vehicle.

  • A CARDET sensor(301/501/LD) simply can be attached on a wall of the booth or a pole, which does not need a expensive ground construction.

  • CARDET has a semi-permanent product life cycle unlike the loop coil that has a product life of only 2 years on average.

  • ​It takes just 10 minutes to install a CARDET sensor and the performance does not depend on the skill of the worker unlike a loop coil.

2. Control of the barrier in an access controller​

CARDET sensor(301/501/LD) can detect the exact timing of passing a vehicle in front of the access control device. In the case of bump to bump traffic, CARDET generates an accurate trigger signal unlike a loop coil for the access controller to handle the barrier bar.

  • A CARDET series sensor has various functions inside of adjusting delay, number of filters and sensitivity to find out the optimal mode for the road situation.

  • A loop coil cannot detect the exact timing of passing of the edge of a vehicle, meanwhile, the digital proximity sensor and FS magnetic sensor in a CARDET-301 can find out the edge of a car accurately.

  • For the special case of the road for large sized trucks and containers, the dual sensor package for access control is prepared.

Above short movie shows the control system of a gate that was installed in Singapore. CARDET-101 opens the gate, which was buried under the pavement and CARDET-301 closes the gate when the vehicle completely get out. CARDET series is the best solution that replace the LOOP COIL with low cost and high reliability.


2-1 Special Vehicle Detection Equipment

  • Trucks or trailers have a plenty of empty space on the side and lower body, so it is necessary to hold the detection signal until the vehicle completely pass out, when controlling the parking barrier.  

  • Special Vehicle Detection Equipment enables the system to sustain the parking barrier open until the large-sized vehicle completely passes out.


3. Car detection for a drive-in-restaurant

Usually in drive-in-cafe or restaurant, number of cars wait and go with bump to bump situation. Conventional loop coil cannot distinguish the two vehicles with a close interval. CARDET-301/501 is the perfect sensor for this kind of restaurant and moreover it can easily be embedded in a menu box on the shoulder of the access road.

  • A CARDET-301/501 does not be influenced by snow, rain and humans, also it has no worry about being destroyed by a snowplow.

  • In South Korea, number of famous drive-in franchise such as Starbucks, Subway, Pizzahut, Burger king, Twosome place, Coffeebean, Pasccuchi etc. already use CARDET-301/501 system.

  • CARDET-301/501 is the perfect sensor for the drive-thru headset system, because it does not need ground construction that is obvious obstruction for customers.

  • CARDET-301/501 supports the easiest way of wire connection for the headset systems.

4. Control of a alarming light for the safety

Safety cannot be compromised in our daily life. In the every corner of a parking building and exit, an alarming light should be installed for the safety of pedestrian and vehicles. Everyone can easily install a CARDET sensor in a 10 minutes for our family and people.

  • A CARDET-301/501/LD detects a vehicle coming to the corner and control the alarming light to let them know it. A smart relay controller for various purposes is included in the sensor box with the default option.

  • CARDET sensor has the function inside to adjust the running time of the alarming light for the convenience.

5. Wireless parking system : CARDET-CP

  • CARDET-CP system is the wireless solution in the parking area using IoT communication technology.

  • It embedded the ultra low-power Pulsed Coherent Radar system with a battery supply of max. 5 years. The sensor module is installed in the center of a parking space(buried type). 

  • CARDET-CP system has two models, one is direct internet access model using NB-IoT technology, and the other is LoRa model which is connected by a gateway.

  • CARDET-CP system is the integrated system with local wireless network, please contact to

6. Vehicle Counter :  V-COUNTER

V-COUNTER counts the current number of vehicles those remain in the parking place. It precisely counts the number of IN/OUT vehicles from the parking place, and connected to the user's system by LAN protocols. It uses two CARDET-301Hs per one channel those specially developed for the function of counting.


  • Cars has variety of shapes and heights, CARDET-301H can detect precisely the front edge of the approaching vehicle even in bump-to-bump situation, so it makes possible that detect the exact starting point of the vehicle which is essential to the counting process in a parking space.

  • V-COUNTER is also embedded of elaborate  digital filters designed from analyzing of vehicle dynamics and sensor characteristics. V-COUNTER records 99% accuracy on normal situation in a parking space.

  • It contains the elaborate parallel processing algorithm for a bump-to-bump, reverse/backward moving, back-and -forth etc situations, so it shows the superior performance of vehicle counting with a great accuracy.


  • V-COUNTER(2CH.) has the unique function of counting cars on both directions where the road is wide and there is no median barrier.​

  • We have also V-COUNTER-LD model for the wide road (max. 10 meter or 7 meters depend on the configuration of installation)

7. Detection of the direction of a vehicle

Using a direction detector, user can easily build up an user's own system for various functions. For example, it is possible to take a picture only when a vehicle exit on the two-way-traffic road. It uses two CARDET sensors(301/501/LD), and has two relays for the easy interface for two jobs for in and out respectively.


  • Direction detector also can use two CARDET-LD sensor for a wide two-way-traffic road which is impossible for the conventional products.

  • Direction detector has two independent relays for the functions of coming-in and going-out respectively, so two functions can be easily interfaced and executed.

8. Customized System( ex. Compact Vehicle Detector )

MAGO technology has various kind of developing user customized vehicle detection systems. Please contact us for developing your own systems. CV-DETECTOR measures the length of the approaching vehicle precisely, and automatically distinguishes a compact vehicle from various kinds of car. Many of the country have a discount policy of parking fee for a compact car to encourage saving energy. In Korean law, one of the necessary coundition to be classified as a compact vehicle is that it has a shorter length of around 3.8m.

  • CV-DETECTOR has a special kind of edge detection structure for precisely measuring the entire length of a vehicle.

  • It uses 2 CARDET-LDs, 1 CARDET-101 and a Signal Processing Controller. CV-DETECTOR also has a function of making a trigger signal for the LPR system, so user does not need to install an additional loop coil for triggering the LPR system.

9. Pulsed type LASER sensor :  CARDET-LD

  • CARDET-LD sensor is a pulsed LASER type sensor that uses time of flight principle for the measurement. It does not be influenced by the shape and color of the vehicles unlike the conventional infrared sensor. 

  • The maximum detection distance of CARDET-LD is 15 meters(with reflector), so it can cover the wide areas which is impossible for the conventional car sensor.

  • CARDET-LD can be installed for a charging station to detect the EV parking space is empty or not. 

  • Also CARDET-LDs can accurately measure the traffic information installed on the gate of the highway without disturbance to the through traffic.

10. CARDET Application  - Detection of a FORKLIFT

  • CARDET sensor can detect a FORKLIFT vehicle in a crowded logistics center. It is very hard to pay attention to surroundings simultaneously with manipulating the FORK.

  • CARDET can easily protect the peoples in the logistics center with very low cost.
