Wireless Sensor Networks (WSN) from Controls Online enable Wireless Sensors, I/O, Serial and Ethernet Communications
Controls Online are experts with Wireless Sensor Network (WSN) hardware and software.
We develop, manufacture and distribute cutting edge and robust devices.
At this layer in
IIOT (Industrial Internet of Things) – data from individual sensors with current, voltage, pulse or digital outputs or devices that have serial communications (i.e. PLCs) is transmitted and received over wireless protocols and can be transferred to a gateway
or another device (Router, Modem, RTU, PLC, or directly to an IPC). It is also possible to control devices over the Wireless Sensor Network via remote IO or embedded into control devices.
Controls Online offer Zigbee and WiFi protocols for our Wireless Sensor Network Devices
Wireless Gateways, Repeaters, Wireless IO Nodes (external to sensor, for wiring sensors into), Wireless Sensors (wireless capability inbuilt into sensors). At this layer and above - network security is highly important, which is why Controls Online uses standardised and encrypted data transmission protocols.
Common License free radio frequency bands in Australia are 433MHz, 915MHz and 2.4GHz.The most common industrial Wireless Sensor Protocols at present include Wireless HART, WiFi and Zigbee.
Benefits of using Zigbee for Wireless Sensor Networks
The standardised Zigbee protocol is
industrialised, low power for battery saving and more secure than WiFi.As your technology partners, we aim to build a relationship with you.
Controls Online offer both Zigbee and WiFi, plus protocols such as MODBUS over wireless network. We also have 3G/4G available at our gateways and directly on our RTUs.
There are other protocols such as Bluetooth and many proprietary protocols, however in our opinion the cons outweigh the pros for industrial applications as these protocols are not robust, scaleable or open enough for industrial use. Closed or proprietary protocols are not governed by any neutral body or alliance and therefore are not continually evolving with relevance to the rest of the world.
We offer Zigbee, due to it's inter-operability and standardisation as a protocol and because it is well supported globally.
Zigbee has some excellent features – the nodes can talk to each other directly, without going through the gateway (peer to peer communication). They can also form a wireless mesh – the sensors themselves can be used as repeaters – extending the network range and increasing the robustness of the network.
