IoT Sensors

Nature has provided humans with unique finger patterns.However, we do not have organs that can detect fingerprints.This may be because humans have some different advanced abilities to recognize each other.Until recently, the Touch ID sensor in our phones was one of the most reliable methods of user identification.This is an exemplary case of how the sensor industry can transform naturally available content into collectible data.

The list of IoT sensors continues to expand as sensor manufacturers continue to look for more and more signals that can be detected and exploited through various IoT solutions.As the computing power of IoT processors continues to increase, new IoT sensors are starting to combine entire clusters of signals.For example, advanced security and monitoring systems are not limited only by optical sensors - motion, temperature, infrared radiation, sound and weight constitute attributes that can be detected, measured and identified by sophisticated IoT solutions with appropriate sensors.To name a few, the following sensors are popular among many IoT solution providers:

·  Proximity sensor

·  Infrared sensor

·  Humidity sensor

·  Gas sensor

·  Weight sensor

·  Vibration sensor

·  Temperature sensor

·  Liquid level sensor

·  Pressure sensor

Proximity sensor

The exact distance between objects is what the proximity sensor can detect.The range of applications for this sensor is huge because the space we live in is very large - it's three-dimensional.The method of determining proximity depends

on numerous factors that are entered in each given situation.This is why proximity sensor manufacturers can choose between different basic technologies offering sensors such as capacitive, inductive, ultrasonic and

optoelectronic.Everyone is probably familiar with how proximity sensors work, and when you need to mount your car to a free parking spot in the city center, the car is usually parked on the bumper.The automatic parking feature inherent

in some non-budget vehicles is a good example of an IoT application of proximity sensors.

Infrared sensor

Infrared sensors can work in two directions: detecting external infrared radiation and emitting infrared radiation externally.This sensor can detect surrounding objects by capturing the heat emitted by the latter.Our eyes cannot detect the

heat emitted by the human body.This is why infrared sensors give us the unique ability to see through walls.Many Hollywood sci-fi blockbusters (Terminator, Predator) use infrared visuals to add impressive superhuman abilities to their

characters.

In real life, IoT infrared sensors are widely used in wearable devices (smart watches) to measure pulse and blood pressure.For example, many IoT solutions in healthcare are based on infrared sensors when blood leaks should be

detected or body temperature measured remotely.Industrial IoT applications of infrared sensors mean remote operation of overheating alarms as well as non-contact temperature measurement.

Humidity and Gas Sensors

These two types of sensors can be grouped for some reason. Both can detect leaks of water or gas.Both are used in various air quality control systems that are becoming increasingly popular in emerging urbanization.The recent hype

around climate change has created a growing demand for smart IoT solutions capable of monitoring both indoor and outdoor living conditions.Furthermore, one of the implicit drivers for the widespread use of such gas sensors, such as

carbon dioxide detectors, is the contemporary "employee efficiency boom" inherent in corporate business units, where human availability is directly related to workplace air quality.IoT-based smart ventilation, capable of automatically

regulating carbon dioxide levels, has become a must-have feature in public spaces such as libraries, gyms, shopping malls, hospitals, and corporate offices.It goes without saying that humidity and gas sensors are essential for air quality

control and monitoring systems.

weight sensor

We live on a planet with considerable gravity, which imposes certain limits on the mass of physical objects.That's why no terrestrial creature could be bigger than an elephant today.Weight measurement is important in the field of

construction.Because the overweight detector has to leave the overcrowded elevator somewhere in the commercial center, it starts blinking if you're there.The weight sensor can safely utilize the elevator.Without IoT weight sensors, IoT

based automation is difficult to deal with in every industry that does bulk loading: excess weight is dangerous for dump trucks in open pit mines and glass ampoules for pharmaceutical companies.

Vibration sensor

Vibration sensors help determine safety levels in industrial equipment, no matter what type of motion occurs.In fact, after the invention of the wheel around 2000 BC, spinning became the dominant type of movement in any industry.Even

very precise rotating mechanisms generate more or less strong vibrations.Predictive maintenance, as well as the self-analysis capabilities of robotic production lines, constitute a broad field of IoT technology providers.Whoever controls

the vibration controls the cost-effective uninterrupted operation of the equipment and its overall longevity.Therefore, IoT vibration sensors as an integral part of industrial vibration diagnostic systems bring hidden but important benefits by

reducing the risk of accidents and unplanned downtime.

Temperature Sensor

Every automatic fire suppression system includes temperature sensors.Smart IoT solutions for public spaces (smart offices, smart stores, smart gyms, other smart devices) are inseparable from temperature monitoring.While primitive but

reliable bimetallic temperature sensors can only signal a noticeable temperature increase in the event of a fire, accurate temperature measurement for automatic air quality control requires more sophisticated digital IoT temperature

sensors.Temperature sensors are the basis of modern heating and conditioning systems in houses and transport vehicles.What is the essence of a fancy smart thermostat? Nothing but a set of temperature sensors and data transmitters.

liquid level sensor

Another cause of global climate change is more frequent flooding around the world.Arctic ice is melting and sea levels are rising. Water level detection has become critical in coastal areas.Early detection and prediction of floods is an area

where IoT solutions can help a lot.The level sensor constitutes the primary endpoint where the water level data starts to run through to the analysis software.

Generally, liquid level sensors are widely used in many fields where people deal with liquid substances.The fuel gauge in your car uses a similar level sensor as the giant gas tank at the gas station.The automatic dispensing of any liquid is

usually based on the signals of two sensors: the upper sensor and the lower sensor.Capacitive and optical working principles are often used for level sensors.We use level sensors multiple times a day to have an effect on our toilets: when

its floating level sensor blocks water supply, the toilet tank stops water supply.

Pressure Sensor

Those who travel a lot by plane know well that when your ears look full of cotton can be uncomfortable.A slight decompression in the cabin creates this feeling.This means that the air pressure on a plane is not the same as our natural

pressure level on the ground.In this case, the pressure sensor may not be working properly.Since pressure as a physical property belongs to gases and liquids, the list of domains using pressure sensors is really impressive.Both domestic

and industrial applications exist there.Automatic pressure control involves the safe operation of such heating equipment, such as boilers, water heaters and radiators.Blood pressure sensors are integrated in numerous smart devices for

medical diagnostics.Tire pressure indication is a fancy IoT feature inherent in modern smart cars.Even the daily weather forecast is incomplete, with no barometric pressure. In every case, IoT pressure sensors can be used.
