GENERATION OF ELECTRICAL ENERGY FROM BIOMASS 1.1. INTRODUCTION Energy is the most vital issue for all living-being on earth. Modern life style has further increased its importance since a faster life means a faster transport, faster communication, faster manufacturing processes etc. All these lead to an increase in energy required for all these modern systems. These energy come from different sources and one of these sources is the biomass or biofuel energy production (generation) source. 1.2. DEFINITION OF BIOMASS Biomass or Biofuel is a fuel that is developed from organic materials, renewable and sustainable source of energy used to generate electricity or other forms of energy. It is the organic material that is used for the production of energy known as biomass . 1.3. DESCRIPTION  OF BIOMASS The biomass plant is a renewable source of energy because wastes residues will always exist be it in terms of scrap wood, forest resources, manure etc...Developing ...

Interfacing a 16X4 LCD In this project, a 16X2 LCD is connected to PORTB of PIC 16F877A microcontroller and the microcontroller is operated from an 8MHz oscillator.

Differences between MCB and MCCB, and characteristics The first thing here is to know the meaning of the abbreviations MCB and MCCB. What does MCB and MCCB stand for? MCB stands for Miniature Circuit Breaker. MCCB stands for Molded Case Circuit Breaker Miniature Circuit Breaker (MCB) It is an electromechanical device used to protect a low load electrical circuit. It is thermally operated and used for protection against over load, heating and short circuits, in circuits requiring a small current rating (less than 100A). It is designed to replace the ancient fuse rewirable device. The Miniature circuit breaker (MCB) functions as an automatic switch OFF device which routinely turns OFF when the current flowing through it passes the threshold (maximum acceptable limit). This is achieved through the use of a bimetallic strip which protects against overload and the use of a solenoid which protects against short circuit. Application of MCB : low load domestic and in...

Interfacing infrared ranger module and object detection using GP2D120 IR sensor and PIC microcontroller Functioning of the IR Ranger Module There are several ways of Measuring range. The easiest way is by using sound waves where ultrasonic sound is fowarded, and is reflected when hit by an object and the time it takes to reflect back is measured. Sounds waves do not travel fast, and can be measured by present day equipment. However, in the case of infrared light, the time it takes to hit an obstacle and reflect back can not be measured because infrared light travels fast. An IR transmitter emits infrared light to the object in front, by passing through a condense lens. Refraction occurs once the light hits the surface of the object. Part of the refracted light falls on the receiver end which is then passed to another lens and processed by an array of photo-transistors. Hence, the position in which the light falls can be used to calculate the distance of an obstacle from the tr...
