Here we propose an automated BMI calculator system that does not need the user to input anything. The user just needs to stand on a platform and the system displays BMI as well as body type of user. The system uses load cells for weight sensing along with an ultrasonic sensor for height measurement. Now the system uses a microcontroller based circuit to get values of user height and weight. Based on the values the system calculates BMI […]
ABSTRACT Majority of earth’s surface is covered with water but less than 5% is useful. So water conserving has become a major issue so certain water management steps are to be taken. Measuring and control of water level is an important task from government and residence side more especially when pumping water in overhead tank. Thus, existing management systems has to be updated [1]. In this paper, we investigate the water level contro […]
ABSTRACT Generally, street or home lights are switched ON for whole night and during the day, they are switched off. But during the night time, street lights are not necessary if there is no traffic. Saving of this energy is very important factor these days as energy resources are getting reduced day by day. Alternatives for natural resources are very less and our next generations may face lot of problems because of lack of these natu […]
ABSTRACT This project is titled the design and construction of an automatic solar water level controller system. The project is designed to give a display of water level in a tank and control a pump motor as required. The reading given is in the scale of 0 to 9. A priority encoder is interfaced to a decoder to get the display of water level on 7 segment display. This is the circuit designed for overhead tank digital water level indic […]
ABSTRACT We live in a world which is moving at such a fast pace that everything if automated will help us to keep our lives going. The project on water level Indicator will help us to know when the water in our tanks is either full or empty and automatically switch on and off the pump as and when necessary. By using the basic principle of ultrasonic sensors, i.e the ECHO method, we calculate the time of the ultrasonic waves travelling […]

ABSTRACT Third eye for the blind is an innovation with the help of the multi discipline subjects like computer science, electronics engineering and health science which helps the blind people to navigate with speed and confidence by detecting the nearby obstacles using the help of ultrasonic waves and notify them with a buzzer sound or vibration. According to WHO 39 million people are estimated as blinds worldwide. They are suffering […]
