How is automotive sensor segment driving the Global Proximity Sensors Market?
Proximity sensors can detect the presence or absence of objects using electromagnetic fields, light and sound. The fact that no physical contact is required to detect the presence of objects results in higher durability of the sensors. With the advancement in technology there are constant improvements in the proximity sensors. They can now be integrated into small chips and be used for a plethora of applications.
The automotive segment of the global proximity sensors market is the most lucrative market in the current times. With the use of proximity sensors in automobiles, travel has become much more safe and enjoyable. Something as simple as the indicator when the children’s back seat door has not been closed properly to a reliable door closure indicator removes distractions and make it much safer for the occupants of a car.
There are various improvements regarding the proximity sensors used in automobile these days. From adaptive cruise control, which allows the car to slow down or speed up depending on the traffic around to parking assist which helps in parking the cars without bumping into the other cars parked behind or otherwise, the way cars are being built is being revolutionised.
Furthermore, the development of self-driving cars will result in a huge boost for the proximity sensors market. There are mainly two types of proximity sensors currently used in cars, namely, ultrasonic sensors and electromagnetic sensors. Ultrasonic sensors use echo-times from sound waves that bounce off from nearby objects and can identify how far the vehicle is from the said object, thereby alerting the driver the closer the vehicle gets. Electromagnetic sensors create an electromagnetic field around the bumper and provide an alert whenever an object enters the field.
There are other numerous sensors used in a car that the car-owner is not even aware of. There is one known as the mass airflow sensor that helps in calculating the volume and density of the air taken in by the engine. This ensures that the right amount of fuel is used for optimised operating conditions. There are other sensors like the engine speed sensor that controls the fuel injection and the timing of the engine and the oxygen sensor which reads the amount of unburdened oxygen in the exhaust pipe. The presence of the spark knock sensors in a car ensures that the fuel is burnt correctly, whereas the manifold absolute pressure sensor measures the manifold pressure outside and inside. There is also a fuel temperature sensor which ensures the right amount of fuel is injected to keep the motion of the car smooth and the voltage sensor which manages the speed of the car and makes sure it is controllable.
The rising adoption of cloud-based technology and the penetration of the Internet of Things in the market are expected to increase the growth in the global market. The proximity sensors can operate in extreme conditions such as excess heat and the integration of artificial intelligence in the sensors are the key factors that are driving the growth of the global proximity sensors market.
