Vehicle Detection & Control

Vehicle Detection Loops, Microwave & Ultrasound Sensors & LED Traffic Lights
LED Traffic Lights

If you need to detect vehicles and control their movement around your factory or car park, we have a range of solutions that can help you with this requirement.  Within our range we have conventional inductive loop detectors, microwave motion sensors and simple photoelectric sensors, which can be coupled to an LED traffic light to control vehicle movement or trigger gates, doors or barriers.

One of the most popular ways to detect vehicles for triggering the opening of barriers, bollards or gates are inductive loops sealed into the surface of the road near the access point.  The sub-surface loop is connected to a ProLoop loop detector which measures the change of inductance in the loop, as a vehicle approaches the change in inductance is detected and the output of the unit changes providing the trigger signal for a gate or traffic light.  These units detect any metal objects such as pedal bikes, motor bikes, cars, vans, lorries and fork lift trucks.

An alternative way to installing inductive loops is a Herkules microwave motion sensor.  These can detect the vehicle (or person) approaching or leaving the access point.  They have the advantage that the road does not need to be cut to install inductive loops, but it is important to not that they are only triggered by movement.  They can be programmed to detect the difference between people and vehicles or the direction of travel.

Another detection method is ultrasound sensing found in the USVD Driv Thru Vehicle Sensor.  This unit detects the presence of a vehicle in a drive through lane, like the microwave motion detector it is much less expensive than loop detectors. The USVD is simply mounted on a post and aimed at the location where a vehicle would pass.

The most simple method of detecting the presence of an object, is a simple photoelectric sensor.  The output of these devices change when their beam is broken by a vehicle or person.  They cannot detect the difference between a vehicle or person, but are a simple way to triggering a gate as part of an overall control system.

All of the above methods are complemented by our range of DokTek LED Traffic Lights.  The Ultra-Bright LEDs used in the traffic lights are idea for use in bright sunlight and of course in the rain of our British climate!  They are simply controlled by providing a 24Vdc power supply to the LEDs and in conjunction with the Traffic Light Control Board, either with or without vehicle sensing, provide a simple traffic control solution around car parks and factories.

LED Traffic Lights

LED Traffic Lights

Our LED traffic light solutions use ultra-bright LEDs mounted in 100 mm and 150 mm circular arrays which provide excellent visibility in daylight and sunny conditions.  They are totally encapsulated in epoxy resin providing excellent environmental protection against water and dust ingress.

Motion and Presence Detector

The Bircher Helios 2T microwave motion and active infrared (AIR) presence detector is a versatile solution for detecting pedestrians and vehicles. The Helios 2T is controlled by a smartphone app making it incredibly easy to programme, it can also be mounted between 2m to 6m from the ground giving installers a wide range of installation points.

Microwave Motion Detectors

The Bircher Herkules 2 and 2E microwave motion detectors are suitable for industrial doors with rapid reaction times, they are ideal for high-speed doors, traffic light control and automated access to car parks.  The unit is suitable for mounting heights from 2.5m to 7m and operating temperatures from –30°C to +60°C.


The 2E also features additional options such as pedestrian access and "Exit Pulse" function for more rapid closing.

CarSense303 Vehicle Sensor

The CarSense vehicle detectors from EMX allow for the detection of vehicles to open gates and barriers. With easy installation below or above ground, these units are the perfect alternative to traditional inductive loop detectors. The unique Detect-On-Stop feature also allows for the operation of doors and gates only when a vehicle has come to complete stop in the detection area, making this a perfect option for applications where there are many vehicles moving about such as busy loading areas.

Drive Thru Vehicle Sensor

Drive Through Ultrasonic Vehicle Detector

The USVD-4X Drive Thru Vehicle Sensor uses patent pending Triangular Planar Array (TPA) technology to detect the presence of a vehicle and/or pedestrian. It is an alternative to using a photoelectric sensor, where you need to detect the presence in one plane rather than breaking a beam.
