Types of IoT with Use Cases
Based on the scope of use, connected devices are divided into consumer and industrial IoT.
Consumer IoT devices are smartphones, smartwatches, trackers, and home appliances. There is currently a boom in consumer IoT. For example, shipments of wearable devices grew 17 times from 2014 to 2022. In 2022, 321.9 million wireless headphones alone were sold worldwide.
The Industrial Internet of Things (IIoT) is a variety of gadgets that improve the efficiency of industrial systems in manufacturing, processing, medical, agricultural, automotive, logistics, and many other areas. There are fewer IIoT devices than consumer gadgets, but they are much more expensive.
Consumer IoT devices are typically designed for a short lifespan, whereas integrating IIoT into production processes ensures they operate for many years. Businesses and consumers can effectively use many solutions without attributing them to one group.
The geolocation system for people and asset tracking can serve various purposes. Initially designed for mines, miners attach the device to their clothing. The gadget picks up signals from nearby Bluetooth beacons and transmits its ID over the Wi-Fi network.
Thanks to the Bluetooth, GPS, Wi-Fi, and 3G used by the IoT system for communication above and below ground, it is always known where the gateway is.
The connected device consumes little power, has a waterproof and shockproof case, and can operate in high humidity, low temperature, with a poor GPS connection, and in the absence of a 3G signal. All these characteristics make the IoT system demanded not only in mine safety but also in many other industries.
Short & Long Range
Connected worker technology is projected to add $59 billion to the global mining industry from 2016 to 2025. Connected devices use different wireless technologies to communicate, forming short-range and long-range IoT groups.
System requirements dictate the choice of communication technologies and protocols, with many devices utilizing multiple technologies. Short-range wireless technologies include Bluetooth, Bluetooth Low Energy (BLE), Wi-Fi, and mesh networks such as Zigbee.
Short-range IoT objects are the most popular worldwide, accounting for around 80 percent of the total number of devices. Experts expect short-range technology to maintain its leadership position in the coming years.
There are cellular (NB-IoT and LTE-M) and non-cellular (LoRaWAN, Sigfox, etc.) versions of Low Power Wide Area Network (LPWA) technology. LPWA-based chips have powerful processors and more memory than short-range SoCs.
Manufacturers often combine short- and long-range technologies in the same IoT system to maximize value. Engineers have used BLE, cellular networks, and LoRaWAN for custom agricultural IoT development. An IoT system consists of independent parts with separate functions and various wireless technologies.
Sensor-equipped devices are installed on hay balers to track the number of bales collected and provide farm vehicles’ geolocation data. The Qt mobile application, using BLE to get IoT data, displays the GPS coordinates of hay bales and agricultural equipment on a map. It also provides users with statistical information. The data is stored in an AWS database.
The sensors placed in warehouses next to the hay bales send temperature and humidity data via LoRaWAN to the AWS server. Numerous sensors inside the drying chambers transmit data to the farmer using BLE or cellular communications, depending on the distance to the dryer.
Thus, a multi-component agricultural IoT system uses various communication protocols for effective functioning.
