Capture measurements for items and store them as data caching

Hello, I'm looking for a freelancer to help me capture measurements for my items and store them as data caching. The items I would like to measure are water levels. I have a specific method in mind for capturing the measurements, and I would like the data caching system to store the information locally and then submit the data using a REST API. I'm looking for someone who is experienced in this field and can help me create an efficient and accurate data caching system. Please contact me if you are able to handle this project. Thank you.
