Evolution of technology has always remained the prime concern of businesses. When it comes to the telecom industry, the tech is evolving at a rapid pace. IoT is the new buzzword in the industry and operators, both big and small, are trying to make the most of the opportunity presented by it. IoT sensors form an integral part of the IoT universe and it is essential that operators create the right infrastructure that enables optimal sensor performance.
Types of Sensors
Sensors are vital for the rightful performance of an IoT platform. There are different types of sensors that form a part of the IoT universe. Below is a list:
This type of IoT sensor is often used in smart phones to switch off the display for preventing the accidental pressing of the keypad. These sensors are designed to detect the movement of an object without any direct contact. A proximity sensor emits infrared rays for detection. Another implementation of a proximity sensor is in retail where it can alert the user about a possible discount when he passes the aisle where the discounted product is stored. It can also be used in parking lots to inform car owners about the availability of parking space.
Temperature IoT sensor is extensively utilized for detecting heat. It is ideal for detecting temperature changes and taking the necessary action accordingly. For example, it can be used to detect the temperature of goods stored in a refrigeration compartment. Whenever the containment unit malfunctions and the temperature becomes unfavorable, the IoT sensor sends a notification to the manager informing him about the situation or automatically triggers failsafe mechanism to prevent damage to the stored items.
This IoT sensor is used for measuring angular velocity and speed of rotation. Gyroscopes are often utilized in car navigation systems and anti-skid systems. They are also utilized in gaming systems like Wii for detecting controller input.
Many industrial operations require the measurement of pressure at all times. Any change in pressure needs to be reported for ensuring optimal operation. Pressure is a measure of force exerted per square unit of area, and it can vary because of a number of reasons. In commercial applications where leakage of liquid can be a factor, pressure sensors can be implemented for checking on leakage. The pressure sensor connected to the local server informs the overseer about the current status, which allows him to fix the problem.
Optical sensors are the most extensively used sensors in industrial operations. An IoT optical sensor transforms optical light rays into an electrical signal. In other words, it converts the incoming light signal into a digitally readable form, which can be measured easily. This property can be put to good use in industrial applications like LASER, alarm systems, mining and refineries.
Smoke sensors are a great way to prevent fire. A smoke sensor can detect smoke and its level. Primarily, there are two types of smoke sensors: ionization and optical. These sensors activate when the smoke level rises, and an alarm or notification is sent to the fire department or the people in charge.
The Importance of IoT Platform in IoT Sensor Performance
IoT sensors have transformed workspaces and influenced industrial operations. But, for an IoT sensor to perform well, it needs a cutting-edge platform. Below are some essential features of a quality IoT platform that every telecom operator should look for:
Versatile M2M connectivity
Machine to Machine connectivity is the building block of an IoT network. Different IoT use cases require different types of connectivity solutions to ensure optimal operation. Mostly, IoT sensors require high-speed and low-latency connectivity to ensure continuous and error-free communication. But, there are other business cases where IoT sensor discharge can become a matter of concern and you may need low-speed and low power consuming IoT connectivity. Therefore, you should always look for a platform that is capable of delivering M2M connectivity exactly as per requirements.
Security of the sensors
The sensors disseminated over the IoT universe store personal information of the people using them. Also, there are many sensors that are critical to life e.g. an IoT pacemaker inserted into the body of a patient suffering from heart ailment. To ensure IoT sensors work as intended and do not compromise the user information, it is essential to implement robust encryption that prevents hackers from accessing the critical data. Cutting-edge security measures like AES and WPA2 are ideal for thwarting hack attempts made on IoT devices.
OTA firmware upgrade
A myriad of IoT sensors are connected as part of the IoT network. It is almost impossible to upgrade all the sensors manually under direct supervision. Therefore, an IoT platform should come with OTA firmware upgrade capabilities. OTA or Over the Air firmware upgrade keeps every device and IoT sensor updated without any direct human involvement.
IoT Sensors: Revolutionizing the Way Industries Operate
IoT sensors have become a vital part of industries across the globe. They have immense potential to change the way work is done. Below are some existing implementation of IoT sensors in various business and household operations:
Telematics is an IoT-powered implementation that can work wonders for automobile insurance industry. Telematics can transmit driving data in real-time to the insurance company. This data can be analyzed, based on which the insurance company can set the premium for the policy. If the driver is too rash, the premium can be set high.
The vast areas of land used in farming can be hard to monitor in real-time. But, with IoT-powered drones, it is possible to analyze the land from afar. The drones can collect the data and forward it to the farmers. The information received can be used for devising new strategies. For example, if the crops are infested by pests and showing signs of deterioration, then farmers can spray the necessary chemicals to clear the infestation. Or, if an area of land is not receiving proper irrigation, a tube well can be constructed at that site.
Storage of perishable goods in retail business
Selling perishable goods requires you to monitor their condition at all times. When the temperature is not ideal, the stored goods may decay or rot. Hence, it is essential to monitor their condition in real-time. For such cases, major players in the retail industry are frequently utilizing temperature sensors in their storage units. The temperature sensors trigger an alarm whenever the temperature fluctuates, which allows people in charge to fix the problem before it causes heavy losses.
For basic fitness and monitoring patients
Fitness watches are all the rage now. These watches help people stay fit by letting them know about their blood pressure, heart rate, temperature etc. They also measure calories burnt throughout the day, which is a valuable piece of information for fitness enthusiasts. When combined with IoT network, these watches can be used by physicians for keeping a track of their patients’ health. We are also seeing a rise in the use of IoT sensors in complex medical transplants like pacemakers. IoT pacemakers send heart-related data in real-time to doctors. Based on this data, doctors prescribe future medication and devise their plan of action.
