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 :
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!
