Suggestions for Remote Monintoring of 4-20ma Sensors

Projects General Guidance
1

Hey guys,

I'm after your opinions on a small project I have been working on. I have had a fair bit of experience working on PLCs in industrial applications but am very new to the adruino and microcontroller scene.

My project is basically to remotely monitor a pressure and temperature sensor online via Thingspeak (OR similar website) so that I can go online and check the pressure and temperature 24/7 aswell as hopefully setup alarm points on the website so I can be notified when pressure or temperature is too high / low. The sensors can be read remotely via a 4-20ma current loop.

After a little research I'm somewhat settled on using this setup. Please feel free to comment where ever you think I am going wrong or if something could be done better.

Do you guys think it is somewhat possible to achieve my goal by using these components?

Looking forward to your replies!
Cheers

ESP8266 and BME280.

Can't use the BME280 as I'm not measuring ambient air temp / pressure. I'm measuring a storage tank in excess of 1000kpa with internal temperature sensor.

And the ESP8266. I don't know enough about it. Will it work in with the 4-20ma clicks?

Do you have an Arduino library for this board or are you comfortable writing your own? I just did a quick google, and there is something on github but it hasn't moved for 3 years.

No don't have a library for it, and definately not comfortable writing my own. Any other way of somehow integrating wifi to the arduino?

Have seen a couple librarys for the 4-20ma clicks that seem somewhat popular, was hoping they'd get me out of trouble.

I was even contemplating throwing a but of money out there to see if someone would write the code, any avenues like that available on these forums?

Plenty of choices for wifi. I've used the Adafruit ATWINC1500 breakout which worked well for me. The ESP8266 seems to be a commonly recommended solution, but I haven't used one.

There's a Gigs and Collaboration forum that you might try.

hello did you manage to make your project?
