1. Introduction
Today aims of new technologies are increase and make a work easier. Technical field’s work also is that uses the new technologies because of the technologies are growth like a mushroom after raining. Project flood monitoring system using GSM is the one of new project to introduce to technical field that use GSM system module, GSM modem is specialized type of modem that operates over subscription based wireless networks which is similar to a mobile phone. A GSM modem accepts a SIM card, and basically acts like a mobile phone for the computer. Traditional modem is attached to computers for ‘dial-up’ to connect with other computer systems. A GSM modem operates in a similar fashion, except that it sends and receives data through radio waves rather than a telephone line. in this system we use the GSM send notification to the cell phone person that in charge in this case went its detect the signal from the sensor. With this project we detected increased levels of water in an area and provide early warning to residents about any of flooding, with this we can reduce the cost of flood losses in the event of damage to property.
In this project also we combine SCADA system to make easier the person in chargeto see and monitoring the system. The SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation. A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.
2. Statement Problem
2.1 First case:
Terengganu: A total of 47 flood victims involving 11 families that had been evacuated to a relief centre in Kampung Tasek in Setiu, Terengganu, are still there. A total of 47 flood victims involving 11 families that had been evacuated to a relief centre in Kampung Tasek in Setiu, Terengganu, are still there.
He said precautionary measures were being taken with the Fire and Rescue Department on stand by for any emergency situation. The Drainage and Irrigation Department Malaysia (JPS) has listed high water levels for rivers in Setiu, Marang, Hulu Terengganu, Besut in Terengganu as well as in Sik in Kedah.So far, 450 people in Johor, 48 people in Malacca and 47 people in Terengganu have been affected by the floods.
2.2 Second case:
Kuching: The flood may have receded in most areas but the affected families are now counting their losses. And a family from Kampung Karu, about 38 kilometres along Jalan Puncak Borneo, among those affected by the flood, estimated their loss to be almost RM10,000.
Among the damaged properties, the family claimed, were eight cabinets, a laptop, a motorcar and a motorcycle which were submerged by the flood waters, which rose nearly one metre high within five minutes. The incident happened about 1am on Dec 26 during a heavy downpour
In this case they don’t know went the flood will happen, with this system, the sensor will detect the increase of water at river and give the signal to micro controller and micro controller send the data to GSM and GSM send the notification to the person in charge. After that we can tell to villages about the flood will happen. Therefore people can save their property before the flood
3. Objectives:
· To monitoring flood system with SCADA.
· To ensure GSM can work to send the data to the phone.
·
4. Technical Approach:
From this block diagram, we can look the operation of flood monitoring system, in this project, we use battery as a main supply to all component to operate. Sensor 1and sensor 2 are water level sensor to give the signal to microcontroller PIC and PIC that have been program send the data to GSM. SCADA is a monitoring system to see the operation or flow of project. The valve is to control water flow to the tank.
4.2 Overview Device
4.2.1 GSM modem
GSM modem is specialized type of modem that operates over subscription based wireless networks which is similar to a mobile phone. A GSM modem accepts a SIM card, and basically acts like a mobile phone for the computer. Traditional modem is attached to computers for ‘dial-up’ to connect with other computer systems. A GSM modem operates in a similar fashion, except that it sends and receives data through radio waves rather than a telephone line.
- Besides the dial-up connection, GSM modem can also be used for sending and receiving SMS which is also one of the key features of GSM Modem are as follow:
- · RS-232 Interface
- · Tri-Band: GSM900, GSM1800 and GSM1900
- · Support TCP/IP
- · Support standard extended open AT commands
- · Support GPRS class 10
- · Accept supply voltage from 5 to 12V
- · Support PDU and Text mode for SMS
4.2.2 PIC 16F877A
There are three memory blocks in each of the PIC16F877A MCUs. The Program Memory and Data Memory have separate buses so that concurrent access can occur and is detailed in this section.
The PIC16F87X devices have a 13-bit program counter capable of addressing an 8K x 14 program memory space. The PIC16F877/876 devices have 8K x 14 words of FLASH program memory, and the PIC16F873/874 devices have 4K x 14. Accessing a location above the physically implemented address will cause a wraparound. The RESET vector is at 0000h and the interrupt vector is at 0004h.

4.2.3 MAX 232
The MAX232 contains four sections they are dual charge-pump DC-DC voltage converters, RS 232 drivers, RS-232 receivers, and receiver and transmitter enable control inputs. The MAX232 has two internal charge-pumps that convert +5V to ±10V (unloaded) for RS-232 driver operation. The first converter uses capacitor C1 to double the +5V input to +10V on C3 at the V+ output. The second converter uses capacitor C2 to invert +10V to -10V on C4 at the V- output.
4.2.4 Float Switch (RSF50 Series)
The RSF50 series are compact vertically mounted devices with a single switch point. Mounting is in the top or bottom of the tank from the inside, so access to the inside of the tank is required. Typical applications include printing systems and chemical dosing equipment. They are manufactured in a variety of materials, with a choice of gasket materials to suit most commonly used liquids. The switch action may be reversed by removing the float, inverting it, and then refitting it to the stem.
RSF50 Series Information:
- Vertical Float
- 25 VA Switching Power
- 0.6 Amp Switching Current
- NO/NC Contacts
- Compact Design
- Switching Power (VA): 25 Volt-Amps
- Switching Voltage AC: 240 Volts AC
- Switching Voltage DC: 120 Volts DC

5.2 Gant Chart
Project title: Flood monitoring system using GSM
Below we can see the estimate time to do the project, the project will start on 16 January 2012 and end at 13 September 2012. We take 1 year to complete this project.
6. Conclusion
In conclusion, we hope this project can successful be accept and complete as soon as possible and follow the schedule. By the research that has been done it is good enough for improvement all part this project. Flood monitoring system will be produce because to solve the current situation using GSM module to send the notification before flood happens. In this project also we have monitor the system automatically method if we use manually method wee need to check every time at that place. To improve this monitoring system we use SCADA to see and monitor the system running. SCADA has been create to help we monitor every where in Malaysia. Flood monitoring system can be commercial because it can help government to reduce losses went flood happen.
