Sensor Network

corel_draw over 1 year ago

I am a newbie to the sensor network world. Any advice would be well appreciated.

My sensor has rs485 connector. So I want to relay my sensor data over 4g iot gateway to my mqtt broker (mosquitto) and then to cloud.

I intend to use an rs485 hub to collect sensor readings from multiple sensors.

The pipeline in summary sensor ===> rs485 hub ====> iot 4g gateway =====> broker (mosquitto) =====> cloud

/ My question is:

1) I saw modules called rs485 data logger , are those modules needed in this set up ?

2) are there any other considerations for robsutness of this set up

Links to references hardware :

a) rs484 hub: https://www.alibaba.com/product-detail/PINWEI-Industrial-RS-485-HUB-1_1600879469226.html?spm=a2700.galleryofferlist.p_offer.d_title.7eda43a6OXiLmr&s=p

b) iot 4g gateway: https://www.alibaba.com/product-detail/Ebyte-ODM-E840-DTU-EC05-485_1601113842515.html?spm=a2700.wholesale.you_may_like.1.50a23027Z2gCtw

Please kindly advice, and this is my first post so if I am breaking any of community rules so let me know so I can adjust accordingly.

Thank you!

You might just need to try it and see! (and report feedback to help others). There's zero information there to know if they can be built into a viable solution.

If you've not found any info on these items so far, I think it's unlikely anyone else has tried them, let alone know the long-term reliability of them. They are cheap enough, so it's not a lot of money to try it out. They are not going to be industrial grade products at that price.

Thank you for the feedback. I will try them out and give feedback. The aim of having these cheap module is for testing and non-heavy industrial usage.
I will likely go for industrial versions after testing.
I appreciate your feedback.
