In the past several decades, the world has witnessed some dramatic changes and modifications in technology. You can see bots, sensors, and many other modern ways of fast communication and problem-solving. For example, if you dial Spectrum phone number, you will no longer have to wait for hours to get a solution to your problem. You’ll get a prompt response through the call support or live chat. Isn’t that convenient?
The IoT, or the Internet Of Things, is another such modern advancement. The name is self-explanatory: an internet connection that consists of various “things” like devices and tools. The most important part of this system is the sensor, and this article will discuss how that works.
What is IoT?
Before we dive into the detailed information about the sensors and how they work, let us discuss the concept of IoT first. Internet Of Things is a system that comprises various components. These components communicate with each other through a unique connectivity cloud.
- The user attempts to communicate or demands a task through a user interface.
- The sensors sense or collect the data, and the cloud receives and processes it.
- The cloud then sends a command to the final controller, device, or interface to perform a specific task in response to the stimulus.
What are IoT Sensors?
The sensors in an IoT system play the part of a gateway. They develop communication between you and your computer, transmitting your commands to the machine to perform specific tasks. This communication is in the form of electrical energy and signals. Hence, a sensor senses physical quantities and converts them into electrical signals to transmit them to the server.
If you’re still having trouble understanding what a sensor is, here are a few everyday examples that you are probably familiar with:
- Smoke sensor
- Temperature sensor
- Pressure sensor
All of these sensors receive data from the environment and send them to the server to take appropriate steps in response.
How Do IoT Sensors Work?
There are four steps to how an IoT sensor works.
Step 1: Data Collection
As mentioned earlier, the first thing a sensor does is sense changes in the environment. For example, a smoke sensor senses changes in the smoke levels in the atmosphere. It is designed to monitor these changes and act accordingly. Similarly, a camera with face detection features will sense a face and only then click a picture. A GPS continuously monitors your location and movement to save your information or guide you accordingly.
Step 2: Connection Development
Once the sensor has sensed the information, the next step would be to communicate it to the central server or cloud. The sensor may use various ways to develop connectivity and make the transfer, like Bluetooth, satellite connection, Wi-Fi, cellular network, etc.
Step 3: Data Processing
Now that the connection development is successfully complete and the data is transferring, the next step is to process it. Why is this part integral to the process? Here’s why:
Data processing refers to the part where the cloud interprets the stimulus and understands what it means. Let’s say that the smoke detector sensed increased smoke levels in the atmosphere and sent the signals to the cloud. The receiver’s responsibility is to understand what the signals meant and whether the high smoke is dangerous. Then, the cloud will make appropriate arrangements accordingly.
Step 4: Implementation
Finally, the information converts into utility and serves a purpose for the user. The stimulus results in a response, which could be a warning message in the form of a blinking bulb, a loud alarm, etc. You can even connect the sensors to your smartphone to receive a notification regardless of where you are.
As soon as the system makes the appropriate response, the sensors stop transmitting the signals and return to normal.
The Possible Problems with IoT Sensors:
Let’s discuss a few things that you need to keep in mind when purchasing an IoT sensor.
#1. They are Expensive
IoT sensors are modern technology, and they require expertise, high-quality material, and lots of investment. Thus, naturally, they’re on the expensive side.
#2. They’re Not Always Accurate
Regardless of how high-quality and advanced these sensors are, they are still only machines. Thus, it is not rare that consumers find accuracy problems with these sensors.
#3. You Might Have a Few Security Concerns.
Encryption of sensitive data is an ongoing issue with these sensors. Scientists and manufacturers are trying to improve this situation and find a solution as soon as possible.
