IoT enables devices to gather and then relay information for data analysis. Smart devices are equipped with sensors that collect data. A few common sensors that measure attributes of the physical world include:

  • Environmental sensors that capture temperature and humidity levels.
  • Barcode, QR code, or optical character recognition (OCR) scanners.
  • Geo-location and proximity sensors.
  • Light, color, and infrared sensors.
  • Sound and ultrasonic sensors.
  • Motion and touch sensors.
  • Accelerometer and tilt sensors.
  • Smoke, gas, and alcohol sensors.
  • Error sensors to detect when there’s a problem with the device.
  • Mechanical sensors that detect anomalies or deformations.
  • Flow, level, and pressure sensors for measuring gasses and liquids.

By using Azure IoT services, devices that are equipped with these kinds of sensors and that can connect to the internet could send their sensor readings to a specific endpoint in Azure via a message. The message’s data is then collected and aggregated, and it can be converted into reports and alerts. Alternately, all devices could be updated with new firmware to fix issues or add new functionality by sending software updates from Azure IoT services to each device.
