Mini Elevator Using Arduino
$155.06$141.84An elevator is a platform that can move up and down in vertical direction by a mechanical mean. In the past elevators drive mechanism were powered by stream and water hydraulic piston. In today`s world, there are intricate governors and switching schemes to control elevators. In our project, the arduino microcontroller based elevator system is constructed to simulate as an actual elevator, and it’s designed for multi-storage buildings.

Multilevel inverter
$131.02$108.18The main concept of this inverter is to use diodes and provides the multiple voltage levels through the different phases to the capacitor banks which are in series. A diode transfers a limited amount of voltage, thereby reducing the stress on other electrical devices

OPTIMUM ENERGY MANAGEMENT BASED ON COUNTER, LIGHT INTENSITY & TEMPERATURE SENSOR
$86.54$72.12The project is designed for optimum energy management based on counter, light intensity and temperature sensor. The system also counts the number of persons entering and leaving the room and displays that information on LCD display. Depending on person’s entry as well as exiting condition the room appliances will play their role. The ultimate objective of this system is to save the energy as well as to design automatic room light controller by turning off all the appliances when nobody is there in the home.

PH CONTROL SYSTEM USING ARDUINO OVER IOT
$141.84$122.60Nowadays water scarcity is a big concern for farming. This project helps the farmers to irrigate the farmland in an efficient manner with automated irrigation system based on soil humidity. Humidity sensor is used to find the soil humidity and based on this microcontroller drives the solenoid valve. Irrigation status is updated to the server or localhost using Personal Computer. Java platform is used here for getting information via serial communication from microcontroller and to update in the server. In addition for better cropping system, fertilizers required for the crops, best crops to cultivate for the particular climatic and soil conditions are updated to server at regular basis by monitoring soil PH level, Temperature level of the field area etc., By using PC host, crop is continuously monitored. Also LCD is used to display the PH, temperature and moisture level. This will improve the cultivation method and leads to better productivity.

Piezoelectric Sensor Based Footsteps Power Generation And Mobile Charging OR Load
$110.58$98.56Day by day, the population of the country is increasing and the requirement of the power is also increasing. At the same time the wastage of energy is also increasing in many ways. So, reforming this energy back to usable form is the major solution. In this footstep power generation project, we are generating power with the help of human’s footsteps; this power is then used to charge battery

Power Status Indication Over GSM
$114.19$84.14In this project, an automatic reclose circuit breaker for low voltage usage is designed. The product description is the Auto Reclose Circuit Breaker (ARCB) will trip if the current sensor detects high current which exceeds the rated current for the miniature circuit breaker (MCB) used. Then the fault condition will be cleared automatically and return the power line to normal condition.

Prepaid Energy Meter
$180.30$168.28The 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
$102.17$81.74The 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.
