+RESTful API for water reservoir control developed for the **Semester Completion Work** for the **Systems Analysis and Development** course at the **SENAC Blumenau**.  
+The proposal is to develop a prototype for water control of a reservoirs (cisterns, water tanks, etc.) in condominiums.  
+This repository contains only the business layer of the solution, in which it is consumed through the [interface layer](https://github.com/fredw/senac-tcs-web).

 ------------------------------------------------------------
-- Notify users by email when reservoir reaches a certain level
+- [ ] Notify users by email when reservoir reaches a certain level
+- [ ] Separate this solution in multiple services (following concepts of micro services)
+- [ ] Improve data structure to prevent problems with reservoirs and sensors settings update (considering data already sent)
