  3. 3. Generally we all know that water is more precious resource and also there exist less amount of useful(drinking) water sources in the nature. So it is our reponsibility to control the wastage of water. Inorder to over come the wastage of water we had developed a new project i.e. “water level controller using gsm.” In this project,the sensors will sens the water level and sends the information to the gsm,then it sends to user.Depending upon the received information,user may ON/OFF the motor. INTRODUCTION
  4. 4. PROPOSED SOLUTIONS The sensor will sense the water level and sends the information to the driver of the micro controller. And the micro controller will sends the information to the motor driver and the motor will be set to on/off depending up on the signal . At the same time the GSM will send the message to the user whether the motor is on/off. CURRENT SCENARIO The water is wasted due to over flow. At the same time, power is also wasted.

  9. 9. A liquid crystal display (LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector Common LCDs connected to the controllers sews are 16X1, 16x2 and 20x2 displays. This means 16 characters per line by 1 line 16 characters per line by 2 lines and 20 characters per line by 2 lines, respectively LCD (liquid crystal display)
  10. 10. GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. GSM networks operate in four different frequency ranges. Most GSM networks operate in the 900 MHz or 1800 MHz bands. It is interfaced through TX,RX(P3.0,P3.1) of the microcontroller . GSM(globalsystemformobilecommunication)
  11. 11. It is a level shifter. operates with single 5v power supply. To convert TTL logic, say TXD,RXD pins of the microcontroller thus need a converter chip. It has 4level translators, two of which are RS232 transmitters and two of which are RS 232 receivers. MAX 232
  12. 12. It has a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid. The sensor's resistive output is inversely proportional to the height of the liquid. The lower the liquid level, the higher the output resistance the higher the liquid level, the lower the output resistance. LIQUID SENSORS

  16. 16. To reduce the wastage of water. To reduce the wastage of power. To increase the pump set life. ADVANTAGES
  17. 17. LIMITATION: It works only when the power is in ‘ON’ state. Due to the network problems, the message send by GSM/USER may not be send within the in time. FUTURE SCOPE: By using solar panels we can give power supply to the sensor circuit and then we can monitor the water level during power cut also. LIMITATIONS & FUTURE SCOPE
