Large industrial / warehouse halls require temperature monitoring on many spots. There are 2 kind of sensors you can use:
- RJ11 - 1Wire UNI sensors with max distance 60 meters from the RJ11 port on the (Poseidon2) device.
- RJ45 - RS-485 sensors with max distance 1000 meters, daisychain wiring structure from the RJ45 port on the Poseidon2 4002 device.
- Combination of RS-485 as main bus and Spider unit + 1-Wire 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.
