Top 10 IoT Sensor Types

Sensors are all over the place. They're present in our homes and workplaces, in our shopping malls and even in hospitals. They're integrated into smart phones and are an integral element of the Internet of Things (IoT). Sensors have been in use for quite a while. First thermostats were developed in the latter half of 1880, and infrared sensors have been used since the 1940s. They are now part of the IoT along with its more akin the Industrial Internet of Things (IIoT), are making sensor use an entirely new level.

In general, sensors are devices that sense and react to changes in the environment. The inputs come from various sources, including temperatures, light, and pressure. Sensors provide valuable data and, if connected to an internet network, they could communicate data with other connected devices as well as management systems.

Sensors are essential in the running of a lot of the companies of today. They can alert you of potential issues before they become large problems, allowing businesses to conduct preventive maintenance and reduce expensive downtime. The sensor data can be analysed for patterns, allowing business owners to understand important trends and take and based decisions.

Sensors are available in various sizes and shapes. They can be purpose-built with a variety of sensors built-in to allow users to measure and monitor numerous sources of information. In brownfield settings it is crucial for sensors to incorporate analog and digital inputs to ensure that they can read data from previous sensors.

There are a variety of IoT sensors, and more applications and usage cases. Here are ten of the most common kinds of IoT sensors as well as some of their applications.

1. Temperature Sensors

Temperature sensors monitor the quantity of energy generated by heat in the environment, which allows them to monitor temperature changes and translate these changes into information. Machines employed for manufacturing typically requires the temperature of the environment and devices to be set at certain levels. In agriculture, too the temperature of soil is an important factor in the growth of crops.

2. Humidity Sensors

The sensors in these types determine the quantity of water vapor present in the air's atmosphere, as well as other gasses. The sensors for humidity are usually located in vents, heating and cooling (HVAC) systems that are found in both residential and industrial areas. They are also located in a variety of other places such as hospitals and meteorology stations that report and forecast weather patterns.

3. Pressure Sensors

A pressure sensor detects the changes in liquids and gases. If the pressure changes it is able to detect the changes and relays the changes to systems connected. The most common use cases are leak testing, which could be the result of decay. Pressure sensors are also helpful in the production of water systems since they are easy to spot changes in pressure or drops.

4. Proximity Sensors

Proximity sensors can be used to detect objects without contact close to the sensor. These kinds of sensors usually radiate electromagnetic field or radiation beams, such as infrared. They can also be useful in uses. In retail the proximity sensor is able to detect the movement of the customer and the product that he or she is interested. The consumer can be informed of discounts or special promotions of the products close to the sensor. These sensors can also be used in parking lots of stadiums, malls and airports to inform users of the availability of parking. They can also be utilized on assembly lines for food, chemical and other industries.

5. Level Sensors

Level sensors are used to determine the concentration of substances like powders, liquids and the granular substances. Numerous industries like water treatment, oil manufacturing as well as food and beverage manufacturing factories employ level sensors. Waste management systems are an example of a typical use, since level sensors are able to detect the amount of waste that is in a garbage container or dumpster.

6. Accelerometers

Accelerometers measure an object's speed i.e. the change in the object's speed in relation to the time. Accelerometers also detect changes in gravity. The applications for accelerometers are smart pedometers that monitor driving fleets. They can also serve to alert the system in the event that the object which should be stationary moves.

7. Gyroscope

Gyroscope sensors determine the speed or angular velocity typically defined as a measure of speed and the rotation around an the axis. The most common use cases are automotiveapplications, like car navigation systems and Electronic stabilization control (anti-skid) systems. Additionally, there are motion sensing in games on video, as well as camera shake detection systems.

8. Gas Sensors

The sensors are able to are used to monitor and monitor changes in air quality for example, the presence of combustible, toxic or dangerous gasses. The industries that use gas sensors are mining oil and gas, manufacturing and research in chemical science. One common use for consumers is the well-known carbon dioxide detectors that are found in a variety of homes.

9. Infrared Sensors

These sensors detect the characteristics of their environment by emitting or detecting the infrared radiation. They also can measure the amount of heat released by objects. Infrared sensors are utilized in many different IoT projects , including healthcare because they make it easier to monitor the flow of blood and pressure. Televisions employ infrared sensors in order to interpret signals by a remote control. Another intriguing application is the one of art historians who use infrared sensors for observing the hidden layers of paintings to identify if an artwork is authentic or fake, or altered through an restoration process.

10. Optical Sensors

The optical sensors convert the light rays into electrical signals. There are a variety of ways to use optical sensors. In the automotive sector, cars make use of optical sensors to detect obstructions, signs as well as other things drivers will notice while parking or driving. Optics sensors play an important part in the creation of driverless vehicles. Optics sensors are a common feature in smartphones. For instance ambient light sensors could prolong the life of batteries. Sensors with optical properties are also employed in the biomedical field , for example heart rate monitors and breath analysis.
