Sensor technology has advanced dramatically in the last few years. With the recent rise of work-from-home trends, almost everyone now owns speakers, microphones, and webcams. While they serve different purposes, these devices are nothing more than sensing technology that has become an important part of our lives and has had a profound effect on us!
if you observe your surrounding, you will find sensors everywhere. in laptops, Smartphones, cars, microwave ovens — you name it, and it will probably have at least one sensor inside.
This article is about sensing technology and a few applications where sensor technology plays a key role.
Sensors are basically divided into two types, based on the value they record
The Exteroceptive Sensor
The exteroceptive sensor collects information about the surroundings outside the existing system, the word “Extero” means outside or from around,
- cameras, radar
- sonar sensors
The proprioceptive sensing technology collects the data from the existing system “Proprios” means inner or possessed
Application in Which Sensing Technology Please a Key Role
sensing technology has become an integral part of the manufacturing industry
Sensors enable companies to monitor, control, and automate operations and enhance security. It brings various manufacturing benefits such as improved productivity, upgraded asset supervision, and More responsible manufacturing growth.
The most known sensors for the manufacturing industry include
Heat Sensing Technology
A temperature sensor is an important indicator of temperature changes in any industry. It enables us to examine and control the temperature during the process. These sensors assist us by providing protection against freezing in pipelines by continuously detecting heat conversion to the pipes.
Some high-level temperature sensing technologies display temperature in accordance with varying output voltage.
Invisible sensors are also used to examine the temperature, the temperature is detected by partially seizing the object’s infrared emission.
Pressure Sensing Technology
A pressure sensor is a gadget that measures the ambient pressure and turns the pressure to electrical signals. This signal is a varying voltage or current and the range is also varying for different manufacturers.
Applications in which pressure sensing technology is used are:
- Cylinder tanks
They also play an important role in perceiving leakage in appliances, thus assisting to steer clear of irrelevant loss of property.
Flow Sensing Technology
Flow sensors are used to examine the streaming flow of the gas or the liquid. They compute variations in the physical attributions of the fluid and examine the flow rate with the help of electrical or mechanical subsystems.
They are important for applications where flow control is required,
- in HVAC
- pumping fuel
- Medical Production
and a variety of smart energy applications make considerable use of flow sensors.
According to the study of Argonne National Laboratory, the demand for auto-sensing technology has increased impressively in the market. With the recent growth in electric vehicle technology, systems such as self-driving cars are being implemented, relying completely on auto-sensing technology.
Important sensors that are used in the automotive industry are mentioned below.
A LiDAR typically includes a rotating object and several stacked lights roots and shows the 3-D point cloud map. which is ideal for evaluating scene geometry.as it is an agile sensor with a radiance source therefore not affected by ambient lighting.
LiDAR does not face the alike issue as cameras when operating in low or variable lighting environments.
Proximity Sensing Technology
These are also known as ultrasonic sensing technology.
Proximity sensing technology is used as a parking aid, contributing to safe and convenient parking. Proximity sensors create a loud sound frequency when hit by any tiny obstacles near the vehicle.
MOD_CH101-03-01 is an example of Proximity sensing technology. Its sensing scale reaches from 300 to 1,200 mm and works at a maximum voltage of only 1.98 V.
Oxygen Sensing Technology
In automobiles, oxygen sensors involve computing the amount of oxygen gas in the exhaust of the vehicle. By contrasting the quantity of oxygen in the exhaust gas to the quantity of oxygen in the air, these sensors indirectly estimate the amount of air and power entering the engine. The use of Oxygen sensor technology is not limited to automotive but is also used widely in the medical field as well.
Thanks to recent advances in technology, we have seen a new era of smart sensors.
These “smart sensors” have a central sensor with a microprocessor that sieves or operates the kept data to give an authentic output signal. These sensors act in accordance with some connectivity devices such as Wi-Fi, Bluetooth, and ZigBee.
Image Sensing Technology
An image sensor is a hard-state gadget that can turn photons into electrical signals to show visual images or to store them electronically.
In IoT, these are used for remote monitoring through cameras and when combined with AI, these cameras can recognize and track human faces as long as they are in contact with the camera.
The best example of image sensing technology is OV04686-H67A Image Sensor.
In this world, every surrounding shows some analog trait, like the potency of sunlight or wind.
And technology is progressing toward the digital side due to the efficiency with which digital signals can be rebuilt and transmitted. The development of high-quality sensors is very important at this time and with growing contesting among producers, sensors are becoming easily accessible these days.
What is Remote Sensing Technology?
Remote sensing is a method of obtaining information, analyzing, and observing the physical characteristics of an area by recording its exposure and radiation energy production without any physical interaction with the object under study.
