Developing on a NodeMCU board with Micro Python

I have a problem collecting rubbish and recycling saturation data. I’ve tried developing on existing ESRI apps to collect data and store it in the cloud. Its failed every time.

I’m trying to develop a data collection method that’s manual but digital, easy and cheap.
