Introduction: This application is one of the best solution to monitor the water (or any other fluid) level and to control the associated pump over blue-tooth.

Detailed description: This application is for people or hobbyists those want to monitor the level of water or any fluid and control the pump from their Android phones either in automatic or manual way.

*This application receives the fluid level values over the blue-tooth link. It needs an active connection with the blue-tooth module such as HC-05, HC-06 or any other that is supposed to send the fluid level information gathered by a micro-controller such as Arduino from fluid containing tank.

**Fluid level information sent by micro-controller via blue-tooth module to iFluid application contains integer values ranges from 0 to 100 based on the level of fluid in container.

Technical working:

1. (Hardware side): Working of iFluid application totally depends on the micro-controller based fluid level detection mechanism. Micro-controller will collect the fluid level information from fluid container using transistor based water level sensing mechanism or using ultrasonic sensor such as HC-SR04.

2. (Application side): Note that this application only accepts the fluid level information in terms of integer values those should range from 0 to 100. According to the current level of fluid in container, micro-controller sends the appropriate integer value to iFluid over blue-tooth (that should range between 0 to 100). For example, let us say if container is half filled with water then micro-controller is supposed to send integer value 50 to application.

iFluid application requires your phone paired with blue-tooth module. when you will start the application, it will display the MAC address of all paired blue-tooth devices to select from. Now you need to select the MAC address of your blue-tooth module that is connected with the micro-controller on hardware side.

After that, application will take 3 to 4 seconds to establish an active connection between itself and blue-tooth module. As soon as it establish the connection with blue-tooth module, you need to select the AUTO or MANUAL mode to either turn ON/OFF the pump in automatic or manual way.

After your selection, application will ready to receive the fluid level values over blue-tooth link.

If you select AUTO mode, application will keep the pump ON if fluid level is less than 100%, else it will turn OFF the pump if fluid level reached 100%.

If you select MANUAL mode, toggle button will be enabled for you to manually control the pump at desired fluid levels.

Application sends integer value 0 to micro-controller over blue-tooth link to turn OFF and integer value 1 to turn ON the pump.

Icon of blue-tooth in menu bar will help you to disconnect active connection or to reconnect previous connection.

**Note: In order to extend the range of communication between application and hardware, one can make use of zig-bee modules with blue-tooth modules.
