Basics Regarding Vehicle Detection Sensors

Vehicle detection sensors are electronic devices used to detect the presence of vehicles. Once they sense a vehicle, they send a signal to the control unit. Vehicle detector sensors can be used as safety devices to close or open the door or gate. Vehicle detection sensors are used to allocate resources, manage assets, traffic control, and parking site safety. They help in keeping accurate records of the arrival and departure time of the vehicles. When identifying the appropriate technology to use on your vehicle’s detector sensors, there are factors to consider like size, task, sensor mounting, sensing range, and outdoor or indoor installation. Vehicle detectors sensors are improving vehicle monitoring in both public and residential areas. Determining the suitable sensor is essential to give accurate signals. Provide your car security by opting for ideal detection sensors from

Types of vehicles detection sensors.

Radar sensors

They are used for detecting vehicles on a long-range. They are suitable for outdoor applications. Radar sensors are accurate because they are not affected by weather conditions like rain, wind, humidity, light, and air temperature. They also can detect vehicles that are in motion and stationery.

Ultrasonic wireless sensors

They are suitable for the covered parking area and indoor application. These sensors use sound waves to detect vehicles and objects. For accurate detection, ultrasonic sensors can be installed into the parking ceiling to detect the presence of the vehicle below. The ultrasonic from guarantees the safety of your vehicle.

Wireless magnetometer sensors

These sensors are suitable for both indoor and outdoor applications. They use a passive sensing mechanism to detect large vehicles like trucks and rail cars. They measure changes in a constant magnetic field; for example, when a vehicle interferes with the constant magnetic field, they detect the changes.

Optical sensors

This sensor uses a beam of light to detect the presence of the vehicle. They are suitable for indoor applications. The presence of a vehicle breaks the beam of light between the receiver and the emitter. They can be used to determine if the vehicle has completely left the packing range.

Key factors to consider when installing vehicle detection sensors.

Precision and accuracy

These two terms have different meanings, but they are highly related. Precision is the capacity of the sensor to detect the slightest changes, whereas accuracy refers to the extent to which the sensor can read actual values. The two aspects must be determined accurately to increase the effectiveness of the sensor. Precision and accuracy are often affected by system errors like wiring, signal, and converters.

Weather conditions

Selecting an appropriate vehicles detection sensor, one needs a proper understanding of the environment in which the sensor will be operating. Most sensors are affected by weather conditions such as humidity, temperature variation, rain, and light energy. Select a sensor that can function well without being interfered with by these conditions.

Sensing range

When selecting a vehicle detection sensor, the sensing range should be in line with the physical placement of the sensor. This will help in taking accurate and precise readings. It also optimizes the lifespan of the sensor.


Most vehicle detection sensors need the power to operate. This power may produce sound or vibration that can interfere with the reading hence causing errors.

Size of the target

Vehicle sensors give reading depending on the size of the target object. Some sensors can detect large vehicles, and others can detect minor vehicles.
