Analytics of Things (AoT) is the work of integrating, preparing and analyzing data from connected devices and sensors so it can inform a decision or action. IoT devices generate observations; AoT adds context, finds patterns and delivers useful results to people or systems. The term describes a broad approach, not one standardized architecture or a requirement that every analysis run in real time.
What does Analytics of Things mean?
AoT is the analytics and decision layer built on Internet of Things (IoT) data. A sensor reading on its own may say that a motor is vibrating, a light is drawing power or a vehicle is at a particular location. To be useful, that observation may need validation, comparison with other readings, connection to an asset’s history and interpretation against an operational goal.
Richard Hackathorn defined AoT in a 2016 Bolder Technology report as “the integration, management and analytics of the IoT sensor data required to distill business insights.” The report distinguishes basic operational dashboards from analysis that brings together information across time, locations or organizations and can support predictive insight. Its cases and recommendations are an executive perspective sponsored by Teradata, not a universal standard. Bolder Technology report

Thomas H. Davenport described the purpose as making connected devices and their data actionable, emphasizing the relationship between machine intelligence and human decision-making. Harvard Business Review, June 18, 2015
How does IoT data become useful?
A typical AoT workflow links several activities. They are a way to understand the work, not a mandatory product stack: some systems act locally, while others send information to centralized systems for longer-term analysis.
#1 Best Overall
- Build a 37-Module Sensor Lab: Add motion, distance, light, sound, temperature, touch, display and control functions to compatible UNO, MEGA, Nano, ESP-32 or STM32 projects for prototyping, classroom experiments and maker builds
- Explore Input Sensors and Motion: Experiment with GY-521 motion sensing, PIR detection, ultrasonic ranging, temperature and humidity, DS18B20, flame, Hall, touch, light, sound, tilt, tracking and obstacle-avoidance modules
- Add Displays, Timing and Control: Use the LCD1602, DS1307 real-time clock, joystick, rotary encoder, relay, buzzers, RGB LEDs and infrared modules to build clocks, alarms, counters, status displays and automated projects
- Follow Guided Projects Materials: Use digital tutorial materials, datasheets, wiring diagrams and example code for compatible UNO R3, MEGA 2560 and Nano boards, then adjust thresholds, timing and logic to create custom experiments
- Module-Only Expansion Kit: Controller board, USB cable, breadboard and jumper wires are not included; use 6.5–9 V DC only with the included power module, verify pin requirements before wiring and keep the laser emitter away from eyes
- Collect observations. Sensors and connected devices record measurements, events or location. Depending on the system, a device may also monitor conditions or perform local control.
- Filter and prepare data. Check readings for quality, organize them and decide what to transmit or retain. Filtering can reduce unnecessary data movement and storage, but what is safe to discard depends on the question being answered.
- Add context. Relate observations to relevant information such as an asset’s history, operating conditions or activity at other sites. A sensor stream may not explain what is happening without that context.
- Analyze for a defined purpose. Use summaries, trend analysis, anomaly detection, forecasting or other methods suited to the decision and the data.
- Deliver a result and respond. An alert, recommendation or control signal must reach the person or system able to act. The result can also inform later analysis.
Teradata describes the role of context and organizational information in making device data more meaningful, and presents integrated analysis across data-lake and warehouse environments as one enterprise approach. That is vendor positioning, not a rule that every AoT implementation needs those components. Teradata’s IoT overview
What can Analytics of Things do?
AoT can support different levels of analysis. The right one depends on the decision, not on whether a project uses the label “smart.”

- Describe and monitor: show current readings and trends so operators can see how equipment or a process is performing.
- Detect anomalies: identify readings or patterns that differ from expected behavior and may warrant investigation.
- Predict and plan maintenance: use changes in sensor data to estimate degradation and help schedule inspection or service.
- Optimize operations: use combined data to adjust how assets or processes are run, where the organization can make the recommended change.
- Understand moving assets: analyze location and time-based streams to study fleets or other moving objects.
Examples of IoT analytics
- Building lighting: SAS describes comparing power readings from parking-lot lights to find a light behaving abnormally compared with its peers.
- Solar farms: a SAS proceedings paper discusses robust principal component analysis for reducing data and detecting anomalies while preserving regression-model accuracy.
- Aircraft engines: multivariate sensor data can be used to monitor degradation and support maintenance scheduling.
- Fleets and moving objects: an IBM Research paper describes spatial-temporal analysis of streaming data from instrumented moving objects, with examples including fleet management, autonomous driving and usage-based insurance. The 2016 paper illustrates a technical approach; it does not establish current commercial deployment. IBM Research paper
Hackathorn’s 2016 report discusses cases involving seven corporations and one city government, including operational efficiency, maintenance, energy and service. The report says its cases drew on public articles and anonymous interviews and that the organizations were Teradata customers, so they are illustrative examples rather than a representative measure of results across organizations. Bolder Technology report
Where should IoT data be analyzed: near devices or centrally?
There is no single answer for every use case. Analysis near a device or at the edge can help when a response must happen quickly or when sending every reading is unnecessary. Centralized analysis can be useful when a question depends on longer histories, data from multiple sites or broader organizational context. Some systems combine both.

| Design question | Why it matters |
|---|---|
| How quickly must someone or something respond? | A decision that cannot wait for centralized processing may call for analysis nearer the asset. |
| What data must be sent and retained? | Filtering can reduce transmission and storage, but discarded readings may be unavailable for later questions. |
| What context is needed? | Asset history, activity across locations or business information may require integrating sources beyond a single sensor feed. |
| What is the analytical goal? | Monitoring, anomaly detection, prediction, maintenance planning and spatial-temporal analysis call for different methods. |
| What are the data patterns? | Modeling may need to account for rare failures, imbalanced classes or cyclical changes over time. |
| Who owns the response? | A result has practical value only if a person or system can receive it and take an appropriate action. |
SAS discusses edge filtering, retention choices and modeling considerations; these depend on the use case rather than implying that all IoT data must be processed at the edge. SAS proceedings paper, 2018
How should an organization start an AoT project?
- Name the decision first. Specify what an operator, planner or automated system should do differently if the analysis succeeds.
- Choose measurements that can inform it. Collect data relevant to the decision rather than treating more sensor readings as inherently better.
- Define quality and context needs. Decide how readings will be checked and what asset, operational or organizational information must be joined to them.
- Choose processing and retention deliberately. Match response timing and data movement to the use case; preserve information needed for the decision and future analysis.
- Fit the analysis to the task. Begin with a suitable level of monitoring or detection, and use predictive or more complex methods only when the data and decision justify them.
- Connect results to an owner and action. Determine who receives an alert or recommendation, what they can do, and how the outcome will be assessed.
What Analytics of Things does not mean
- It is not just installing sensors. Collection alone does not integrate, interpret or operationalize the resulting data.
- It does not always mean real-time processing. Some decisions are time-sensitive; others depend on accumulated history or cross-site analysis.
- It does not guarantee a particular business return. The cited examples do not establish a broadly comparable present-day performance benchmark.
- It is not a sharply standardized discipline. Sources use the label for overlapping work, including enterprise integration, edge processing and machine-learning applications.
The cited examples include publications from 2016 and 2018; they illustrate concepts and methods rather than proving that any named deployment remains current. The available sources do not establish a reliable, comparable current market-size, adoption or average-return figure for AoT.
