Monitoring Langelier Saturation Index (LSI) in public swimming pool using SmartOASYS - IoT - Platform as Services (PaaS)

Problems in Public Swimming Pools: 
1. Pool water is cloudy and the bottom drain cannot be seen from the pool deck. 
2. Chemical Imbalance 
3. Pool has no disinfectant residual
4. Mechanical failure - Improperly working filters

Overview: Description of the project

A. Smart OASYS-  IoT Gateway 

Smart OASYS-  IoT Gateway   is an intelligent gateway system which allows easy integration of sensors based on MODBUS, Proprietary Wireless protocols (Sub GHz, LoRA etc) with IOT platforms or cloud using Ethernet or GSM (Optional). 

The application platform can access the sensor data either using SNMP protocol or Gateway can communicate with standard platforms using industry standard protocols HTTP(REST), MQTT.  Smart OASYS-  IoT Gateway  also supports wireless sensors through its 868MHz ISM band interface. It supports a host of wireless environmental sensors, eliminating the need for a wired connection. 

Humidity sensors at the preset intervals and makes it available to the user over SNMP protocol.

Smart OASYS-  IoT Gateway  as gateway can also be configured for connecting to Cloud / IOT platforms using industry standard HTTP(REST), MQTT. This allows transfer of sensor data to Cloud platforms using REST API. The remote management of devices etc is achieved with the inbuilt proprietary software.
