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 IIoT sensors are becoming available, especially for LoRaWAN 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:
- generic input versions are also available to allow interface to standard 4-20mA or 1-5VDC devices.
Sensors come in different package types, IP20 to IP65, low cost and have a long battery life in good conditions. For example, battery life can be up to 2 years using 2 x AA batteries and sampling rate of 20 times per day. They 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
Wireless networks are most commonly used to access new devices that maybe widespread and not connected to the existing control or monitoring systems. Emerging networks such as LoRaWAN are rapidly becoming popular due to their ability to transmit data over long distances, up to 7km in the open and 2-3km in urban areas. Gateway communication devices are used to convert the data into Ethernet and securely transmit the data to the LoRa server via 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 of this information in many ways.
