Most industrial halls and sites have harsh environment, combined with strict regulations reducing risks of fire and explosion. When temperature monitoring is needed, there are more reasons to deploy RS-485 based sensors.
This solution describes, how to monitor environment or process conditions remotely with using of Ethernet for data and alert processing. Industrial sites have usually very complex structure and high level of electric/radio jamming. Usage of wireless IoT sensors does not guarantee operation reliability, usage of full ethernet cabling and active components is not cost effective. Usage of standard industrial RS485 bus for sensor network covers most cases.
