Prepaid Energy Meter
₹15,000.00₹14,000.00The concept of electronic energy meters has been introduced in the power sector to effectively record the units consumed for billing purposes and also monitor several other factors to reduce power theft and minimize losses that occur due to conventional electromechanical energy meters. This is a multipurpose project that integrates all the functions including a prepaid billing arrangement and automatic message sending system to the utility company. It may please be noted that it is truly not ausable commercial product engaging actual prepaid card but uses a set of switches for understanding the technology implemented behind it. This project uses an Arduino to which a GSM modem is interfaced. From here the message is sent to the phone number that is auto-saved by giving a missed call to the SIM number present in the GSM modem. There are a set of pushbuttons, which are used to load,any recharge amount required. Such arrangement is in lieu of an actual prepaid card for demo purposes. By pushing those buttons one can easily recharge the amount. As soon as the Arduino receives any recharge amount, a switch is set, to deliver power to the load. Thereafter consumption of the load power is calculated by the energy meter, which is interfaced to the Arduino through an Optical Isolator IC. The Arduino program then starts to deduct the recharge amount as per the consumption of load power. Once the recharge amount reaches zero then the Arduino cuts the power supply to the load through a relay driven duly by an NPN transistor and also sends a message to the phone number stored that contains all the billing information. Then again the balance is not available then go to the message in the gsm no available in balance

PRIORITY BASED SUPPLY SELECTION OVER GSM
₹8,500.00₹6,800.00The main objective of this project is to provide priority-wise power supply to a load, by selecting the supply source from any available one out of 4 such as mains, generator, inverter, and solar in the absence of power supply. The demand for electricity is increasing every day and frequent power cut is causing many problems in various areas like industries, hospitals, and houses. An alternative arrangement for a power source is thus desirable.

Railway Track Crack Detection
₹12,200.00₹11,200.00India has the world’s fourth largest railway networks, which carry out most of the commercial transport in India. The train transportation increased due to high speed, economical, environment friendly, safety and modern characteristics of railway system. Major problem with this transportation is the bad weather condition, which cause flaws and cracks leads to the damage of railway tracks.

RASPBERRY PI FOR BLIND READER
₹19,500.00₹18,300.00This project has been built around Raspberry Pi processor board. Optical Character Recognition or OCR is implemented in this project to recognize characters which are then read out by the system through a speaker. It is controlling the peripherals like Camera, speaker and LCD which act as an interface between the system and the user. As shown in the project setup, the camera is mounted on a stand in such a position that if a paper is placed in between the area marked by angular braces, it captures a full view of the paper into the system. When the camera takes the snapshot of the paper, it is ensured that there is a good lighting condition.
