Sensor technologies trends and market

A Sensor is an electronic device that is used to measure some sort of physical parameters (e.g. temperature, pressure, light intensity, etc). The output of an electronic sensor is an electrical signal that is either analog or digital. Processing the sensor’s output can be done in hardware (using discrete electronic elements) or in software (using some sort of microcontrollers or MPUs).

 

Sensors are being employed in a wide range of applications. Some of the applications include Automation, Robotics, Embedded Systems, Computers, Smart Cars, Avionics, Satellites, Smart Homes, Smartphones, Smart Watches, Energy plants, Remote Sensing, and Communications.

 

Our smartphones contain a multitude of sensors.  The thermistor inside this phone can sense the overheating of internal circuits and sends a signal to the microprocessor to shut down this phone. Google Maps depend on the GPS sensor in our phones that enables this little app. Proximity sensors placed by the earpiece of your phone tell it when you’re on a call. The phone saves battery power by turning off the screen. The gyroscope enables a compass app, and a capacitive sensor on the touchscreen senses when your finger is touching an icon. A light sensor adjusts the screen brightness here for ambient light levels. And there is a battery sensor here to correlate the charge level in the battery to the present life left on a phone.

 

Dozens of sensors are used in modern automobiles. Temperature sensors monitor the combustion process in the engine, the cooling process in the radiator and your comfort level in the cabin. Pressure sensors make sure you have sufficient oil to lubricate those pistons and proper air levels in the tires to make those wheels go around and you drive safely. A flow sensor makes sure you have sufficient air intake to combust the gasoline, that’s of course if it’s a gasoline engine. Position sensors monitor engine throttle, crank and camshaft angles, and radar detectors are critical features of all autonomous vehicle software. Airbags know when a collision is imminent from the accelerometer inside. And dashboard touch screens, well, they have capacitive sensors too. An oxygen sensor monitors the intake to the combustion reaction in the engine. And the oxygen and hydrogen sensors are used in experimental fuel cells for battery-operated cars. A battery sensor is an essential element of all cars whether gasoline or battery operated.

 

Sensors are in most electronics products these days. They’re driving a technology revolution called, “The Internet of Things.”

 

Sensors Classification

There are, in fact, many classifications for sensors. We can classify sensors depending on the type of output signal or the physical parameters they measure and other considerations could be taken resulting in a variety of ways to classify sensors.

Many types of sensors, detectors, and transducers are available including those for detecting a physical presence such as flame, metals, leaks, levels, or gas and chemicals, among others. Some are designed to sense physical properties such as temperature, pressure, or radiation, while others can detect motion or proximity. They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others.

Temperature Sensors/Detectors/Transducers are electronic devices that detect thermal parameters and provide signals to the inputs of control and display devices.

Vision and Imaging Sensors/Detectors are electronic devices that detect the presence of objects or colors within their fields of view and convert this information into a visual image for display.

Radiation Sensors/Detectors are electronic devices that sense the presence of alpha, beta, or gamma particles and provide signals to counters and display devices.

Contact sensors refer to any type of sensing device that functions to detect a condition by relying on physical touch or contact between the sensor and the object being observed or monitored.

Proximity Sensors are electronic devices used to detect the presence of nearby objects through non-contacting means.

Pressure Sensors/Detectors/Transducers are electro-mechanical devices that detect forces per unit area in gases or liquids and provide signals to the inputs of control and display devices.

Motion Sensors/Detectors/Transducers are electronic devices that can sense the movement or stoppage of parts, people, etc. and supply signals to the inputs of control or display devices.

Rotary sensors. An incremental encoder generates a train of electrical pulses, whose frequency is proportional to angular speed. Homing applications include motor speed and rate control found in machine tools, robots, mixing equipment and textile equipment.

Absolute encoders are routinely used for rotary position sensing. They’re also found in machine tools and robots. But they get used in medical and welding equipment where precise control of position is mission-critical for these applications. The rotating disk within the absolute
encoder contains a very precise pattern that is used to create a multi-bit digital word at each discrete angle at each location.

Position Sensors/Detectors/Transducers are electronic devices used to sense the positions of valves, doors, throttles, etc. and supply signals to the inputs of control or display devices.

Photoelectric sensors are electrical devices that sense objects passing within their field of detection, although they are also capable of detecting color, cleanliness, and location if needed.

Particle Sensors/Detectors are electronic devices used to sense dust and other airborne particulates and supply signals to the inputs of control or display devices.

Metal Detectors are electronic or electro-mechanical devices used to sense the presence of metal in a variety of situations ranging from packages to people.

Level Sensors/Detectors are electronic or electro-mechanical devices used for determining the height of gases, liquids, or solids in tanks or bins

Humidity Sensors/Detectors/Transducers are electronic devices that measure the amount of water in the air

Gas and Chemical Sensors/Detectors are fixed or portable electronic devices used to sense the presence and properties of various gases or chemicals

Force Sensors/Transducers are electronic devices that measure various parameters related to forces such as weight, torque, load, etc.

Flow Sensors/Detectors are electronic or electro-mechanical devices used to sense the movement of gases, liquids, or solids

Flame Detectors are optoelectronic devices used to sense the presence and quality of fire
