Final Project

Description of Final Project

Aim - Dam Water Level Measurement through Sensors and Display on LED matrix

Water Avaibility Display for pabal Villagers.

Discussion on differnt Project idea

In Vigyan Ashram I got Different idea on different projects. I live in a rural area so I know water-related problems for the rural area. I discuss a different project idea of rural development like waste management, food Processing, water recycling with our Director Dr. Yogesh Kulkarni and I also discuss with our Deputy Director Mr. Ranjeet Shanbhag on advanced technology in Agriculture.

When I was discussing with sir, that time I Like the concept of Dam Water level Indicator. When People will see the display in their village, they know water storage in the dam and how should be used.So,I finalised this Project.

Need

Basically, I belong from a rural area. I have seen in the rural area that there is limited water storage due to lack of rain since last 23 years.do not have sufficient water still people do not use properly.so, I am going to make a device that has enough water reserves in the village dam and how much longer it can be used. and it shows on a 7 segment display. this display indicates the storage of water in the dam. People will see this display they will be aware that there is only enough water storage in our dam and we have to use water properly.

Sketch Of Final Project

Project idea in this week Principle and Practices

Working

Block diagram of transmitter side

Water level Sensor senses a dam water level and sends reading to Microcontroller.

Microcontroller send cammand to transmitter side GSM module. A send sms of water level value to receiver side GSM module.

Block diagram of Receiver side

This sms is received in receiver side GSM module. This live sms send to a LED matrix display.

A water level display on LED module.

Solution

The Dam water level indicator is defined as a system which gets the information about the water level in Dam or reservoirs. which is used in cities and villages. By using the water level indicator we can overcome the overflow of water from the Dams.

Project Plan

I have also created a Gnatt chart for project management.It is a online tool with paid and free options.Project plan is very useful to do work on time, calculate the risk, manage the things or inventory and I made gantt chart for my project. Its a six months planning with dates but its very hard to keep with dates.

I made Planning Chart In this week Project Management

This is my project material list.

I made Project material list Application and Implication

Electronic

Design and Fabricate Board

Using Eagle and Rolland SRM-20 milling machine, I made two PCB for sensing Water level sensor. And AT-mega 328 microcontroller Board.I want to measure water level in my project so I decided to make water level sensor in this assignment.

In water level sensor I need 5 connectors for checking level in different steps.So,I took 5 connectors (2 pins header),registors (In one circuit I took two registor) and 8 pin header for input(5 for inputs and 2 for GND and VCC). Firstly I arranged components and join it using jumper wires.then i checked erros.then I got a one error,I cleared it and clicked on switch board.

Then I routed my board and checked the DRC. Here routing is done.

And saved the board in .png format.

I used fabmodules for making .rml file

I learned how to design the PCB. I used Eagle for designing the PCB of the final project. For designing, used Atmega328p IC which has 32 input or output pins fixed on my final board.

Open the eagle softawre and started schematics.my output board of final project is LED Matrix Display.I used GSM Module for sending messege receiver side to transmitter side.GSM module has 3 pins(RXD,TXD and GND),So,I took 3 pin header for output.

A 20Mhz resonator connected across the XTAL1 and XTAL2 pins.Join push button to reset pin and another pin of the switch is grounded.Crystal connected across the XTAL1 and XTAL2, add the load capacitances from the pins to ground. I used Resonator instead for Crystal oscillator because it already has capacitors inbuild.

I used 8 pin header for inputs from sensor.and also used 3 pin header for output(GSM Module).then I used LED for indicator,switch,power jack for supply.

After design the pcb in eagle and export the traces, dimension and dill paths separately, save it as png ( use monochrome mode to export the images )

After opening the traces image in fabmodule and choose use 1/32 bit to mill the pcb.while drawing the traces I gave 0.012 inch as the trace width.

the traces image in fabmodule and choose use 1/364 bit to mill the pcb.

Then milling board.

I have made same board for my Output device

Soldering

What component I used?

Atmega 328p
8 pin connector
4,3 and 2 pin connector

Trial..

design

Casing

We have to do laser cutting assignments. I cut all project related parts in SIL LASER.

After Design I took a trial on Carboard.It pressfit perfectly. Then I was cutting on White Acrylic sheet

Assembly

Then I did Assemble this part.O Dam there is no electricity that why I using battery for power supply.

Transmitter side

Installation

Every Dam have the one Well.With the refernce of this well I am measuring Water level.Dam and well is similar base level.

How I Fitted

Well height is 15m.I took pipe of similar height of well and fitted the sensor in different measurement.

here is the well

I attached the level sensor of pipes

For holding the sensor I used T-slot use in pipe.

Receiver side

LED Matrix

little bit of Times Square into your home with our RGB LED matrix panels. These panels are normally used to make video walls — here in New York we see them on the sides of buses and on bus stops — to display animations or short video clips. We thought they looked really cool so we picked up a few boxes from the factory.

These panels require 12 or 13 digital pins (6 bit data, 6 or 7 bit control) and a good 5V power supply, at least a couple amps per panel.

DMD Connector

This handy Dot Matrix Display Connector allows you to plug an LED panel with a HUB12 interface straight in to an Arduino-compatible board.

I made DIY DMD Connector.following this image.

I made this connector on general purpose PCB.

Features

Suits displays with a HUB12 interface

Pin spacing to suit Arduino compatible headers

Connector for 10-way ribbon cable for DMD (not included)

Arduino compatible library, graphics functions and example support

DMD connector used for the connect the led matrix to board.LED matrix have 8 pin connector for input and output.DMD connector also have 8pin connector.Led matrix connect to dmd connector and dmd connector go to board.

Here is receiver side

I design box casing in solidwork.I drew 6 side plate.

This is the T-slot for holding this LED on Wall.

This plate for the surface mounting

made a dxf file

I made project transmitter part only. And for receiver part I used Arduino Board.

I designed in this week Computer controlled cutting

Here is the code of Receiver side.
