Types Of Information Collected By IoT Devices

The data gathered by IoT devices can vary widely, depending on the function and design of the device. However, there are several common types of information that many IoT devices collect.

1. Personal Identifiable Information (PII)

Many IoT devices collect personal identifiable information (PII), such as names, email addresses, phone numbers, and in some cases, social security numbers. This is often necessary for the device to perform its intended function. For instance, a smart doorbell may need your phone number to send you alerts when someone is at your door.

2. Location Data

Location data is another common type of information collected by IoT devices. This could be as specific as your GPS coordinates or as general as your city or state. For example, a fitness tracker or smartwatch often tracks your location during workouts to provide data on your route and distance traveled.

Video surveillance IoT devices can stream high-definition video data, consuming bandwidth ranging from 2 megabits to 10 megabits per second, depending on the video quality and frame rate.

3. Usage Patterns And Preferences

IoT devices often gather data about how and when you use them. This could include what time you typically turn off your smart lights, the temperature settings you prefer on your smart thermostat, or the type of music you listen to on your smart speaker. This type of information helps these smart devices ‘learn’ your habits and preferences, enabling them to provide more personalized services.

4. Environmental Data

Some IoT devices are equipped with sensors that enable them to collect data about the environment. This could include temperature, humidity, light levels, sound levels, and even air quality. Such sensor data can be used for various purposes, such as automating other devices (like turning on the AC when a certain temperature is reached) or monitoring environmental conditions.

The average IoT device can generate and transmit data ranging from 1 kilobyte to 1 megabyte per second, depending on the complexity of data processing by the sensors and the frequency of data transmission.


How Information Is Collected And Transmitted

Now that we know what kind of information IoT devices might collect, let’s look at how they gather this data and transmit it.

Sensors And Data Collection Methods

IoT devices use different types of sensors and data collection methods to gather information. They may use physical sensors, like temperature or motion sensors, to gather data about their environment. Other devices might rely on digital data collection methods, such as tracking usage patterns or collecting user input. Once collected, this data is typically processed and stored on the device, at least temporarily, until it can be transmitted.

Communication Protocols Used By IoT Devices

IoT devices use various communication protocols to transmit data. These protocols determine how data is formatted, addressed, transmitted, and received. Some common IoT communication protocols include Wi-Fi, Bluetooth, Zigbee, Z-Wave, and Cellular IoT. The choice of protocol depends on factors like power consumption, range, bandwidth, and security requirements.

Data Storage And Transmission Security Measures

With the vast amount of sensitive data being collected and transmitted by IoT devices, ensuring secure storage and transmission is critical. Encryption is a common method used internet connected devices to secure data during transmission. Data stored on the device is often also encrypted to protect against unauthorized access.
