Hello there, thank you for your kind reply. my project is like an an smart water system. i will briefly explain the process flow in here below.
First of all the the designed harvester will collect the rain water.
1) Once rain started to fall, container’s lid will open
2) Rain water will fill in the empty container.
3) There are 2 sensors in the container. one is high and one is low. till it reaches high there is no signal sent to close the lid of the container which is controlled by a valve to push it ( open or close). after the water level reaches the high level the lid is closed.
4) there is a Ph sensor located in the container to check the acidity of the water. Next the pH sensor will detect the pH level of the water.
5) there are one more container will be located which will be connected by a valve. in this container there will be nutrient to shoot in so that the acidity of the rain water becomes okay.
i. If the pH is within range of 6.2 and 7, thus no action is required from the nutrient box
ii. If pH is more than 7 and less than 6.2, the valve connecting nutrient box and rain harvester will open, allowing the flow of nutrient; at the same time controller will trigger the mechanism of stirrer. PH sensor keeps track on changes happen on the pH level of water and transmits data immediately to controller. Once required pH level reached, the controller will force the valve to close the flow from nutrient box and the stirrer will stop.
5) Once the rainfall filling reaches ½ the capacity of the container, the ‘Ready to Use’ indicator will flash. At this level of water and onwards the water from container can start to be utilized.
6) Once it reaches max level, second LED will flash, indicating that the container is full; container’s lid will close.
7) Harvested rain water will be kept in storage until there is an input command trigger from human through switch to stop usage of water from utility meter and replace rainfall water for utilization.
8) Timer placed, will be the controlling factor on how much of water volume intended to shower the plants/vegetation.
9) After a period of time the controller will send signal to close the solenoid valve.
