Grid Power Management Using Electrolyzer This is my final year academic projects (BE-EEE) which I have done along with my projects mates. Objective : The main objective of the proposed system is to store power from available unused energy resources via grid and then supply that stored energy to the grid during power demand.   Need for the project: To maintain the transmission system efficiency this method is proposed. Currently batteries are preferred for storing power        But batteries are very expensive and it has to be maintained periodically And also large amount of power cannot be stored using batteries Existing Method: In India still there isn’t any concept regarding the storage of grid power. When there is no power demand wind and solar plants are turned off whereas nuclear and thermal plants never shut down and excess grid power is dissipated as heat. In some countries process for storing the solar power in the form of hydrogen is in developing stage

The project explains interfacing of the AT89C51 micro controller with the GSM module and the Hyper Terminal. Hyper Terminal is a Windows application. The AT commands are sent by the Hyper Terminal to the GSM module. The Information Response and/or Result Codes are received at the micro controller and re transmitted to the Hyper Terminal by the controller. A GSM module has an RS232 interface for serial communication with an external peripheral. In this case, the transmit pin (Tx) of the computer’s Serial port is connected with the receive pin (Rx) of the GSM module’s RS-232 interface. The transmit pin (Tx) of the RS-232 of GSM module is connected to receive pin (Rx) of microcontroller’s serial transmission pin. And the serial transmit pin of the micro-controller is connected to the receive pin of the computer’s Serial port. Therefore the commands and their results are transmitted and received in a triangular fashion as depicted below. Code :   // Program to interface GSM Mo

SMART IRRIGATION SYSTEM USING SOLAR POWER Abstract: Today technology plays a vital role in improving the performance of every field. Similarly in the field of agriculture some resend technology helps the farmers to monitor and maintain their crops easily. Our project is also based on the maintenance of crops in the agriculture field. Introduction: Though there are pumps which will irrigate water by controlling it remotely, but it requires human supervision, also on the other hand we can’t use fixed timer based motor pumps. Since the pump irrigate water only based on timer, it will never consider humidity of the soil and type of crop used. Since in farming different crops consume different amount of water. Hence we need a system which will irrigate crops on the basis of, ·          Nature of crop ·          Moisture level of Soil. He we designed a system which will compensate the above requirements. Circuit Explanation:  There are six timing control available w

   Do you wanna Enjoy the Comfort of Unix in Windows ?    (without internet)          No need of installing an Unix OS just follow the instruction below Step 1 :Download cygwin installer from internet                          Click here to goto download page Step 2: After Downloading open it Click Install from Internet Choose Direct Connection choose any one of the servers.

Distilled water  is  water  that has had many of its  impurities  removed through  distillation . Distillation involves  boiling  the water and then condensing the  steam  into a clean container.It has variety of applications.Mostly it is used in batteries by the normal people.It is very easy to make So here are the steps to make Distilled water at home.          1.Take a closed jar which has the opening at the top                                ( cooker ,kettle are recommended for this process.)          2.Now add a tube to the opening or just make an arrangement such that the steam should directed toward a plate or surface.Now the steam will be converted into water droplets when it hits the surface.         3.Collect the water droplets in a clean vessel.         4.The collected water is itself Distilled water. Note: In order to get pure Distilled water make sure the tube,flat surface,vessel are free from dust.

Did your UPS/Bike battery got expired ?? Don't throw it you can again reuse it Warning:This method is only for Lead Acid batteries,not for Lithium ion battery My desktop ups battery has expired and it was in dead condition.so I want to recycle the battery …this is a effective way and this method is used in battery servicing stations. it’s so simple and easy..U can do it in your home STEP 1 : things required 1)  Water  (more pure the water more effective outcome better u can use  distilled water )              you can use water that available in your home,but distilled water is more effective                 ( click here for How to make distilled water in home)                                                                           2)  Syringe  (anything which pours water on battery hole) 3)  Dead  battery (be sure that the battery is not in popped condition)    STEP 1 : Remove  the top cover of the battery as shown in fig BEFORE WATER FILLING
