IIoT Hardware and Software
The Industrial Internet of Things (IIoT) makes available more operational and process data, providing useful, realtime information to whoever needs it, whenever they need it, wherever they are.
A wide range of low cost, low power sensors are becoming available, especially for LoRaWAN and NB-IoT networks. Most are powered by battery (or fixed power can be used if available). Battery-less sensors are now being developed that work based on sound or motion energy as well as RF.
Sensors are available to measure:
- GPS tracking
- generic input versions are also available to allow interface to standard 4-20mA or 1-5VDC devices.
- and many other parameters
Sensors come in different package types, IP20 to IP65, are generally low cost and have a long battery life in good conditions. Battery life can be from 10 to 15 years depending on the network used and the sampling rate. Sensors are used in a diverse range of applications including agriculture, heavy industry, water wastewater, city wide power metering, building management and even people movement and product tracking.
Wireless Networks and the Cloud
Low powered wireless networks (LPWAN) are most commonly used to connect devices to the Internet and the Cloud as sensors maybe widespread and not able to be connected to the existing control or monitoring infrastructure. Networks such as LoRaWAN and NB-IoT are the most popular due to their ability to transmit data over long distances, up to 7km in the open and 2-3km in urban areas and good coverage inside buildings.
Gateway communication devices are used to convert the data into Ethernet and securely transmit the data to the LoRa Server and the Internet either via 3G/4G, WiFi, NBN or even satellite.
Data is then accessed via secure Cloud based services like Amazon Iot, Azure IoT or Google Pub/Sub, allowing Visualisation and further analysis of this information using various platforms, including ARDI (Asset Relationships and Data Integration).
