The present day electrical power system is a.c. i.e. electric
power is
generated, transmitted and distributed in the form of
Alternating current. The electric power is produce at the powerstation, which are located at favorable places, generally quite
away from the consumers. It is delivered to the consumer
through
a large network of transmission and distribution. At
many place in the line of power system, it may be desirable andnecessary to change some characteristic (e.g. Voltage, ac to dc

pulsar 220 fi electric circuit

The Bajaj Pulsar is a motorcycle brand owned by Bajaj Auto in India. The two wheeler was developed by the product engineering division of Bajaj Auto in association with Tokyo R&D,and later with motorcycle designer Glynn Kerr. Currently there are five variants available, with engine capacities of 135 cc, 150 cc, 180 cc, 200 cc, and 220 cc. Previously it was also offered with a 200 cc DTS-i oil cooled engine, which now has been discontinued. Instead a new version Pulsar 200NS was launched in 2012. But then Pulsar 2 ....etc

interfacing of humidity sensor with 8051 microcontroller pdf

Abstract

This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16 2 LCD display. A relay is also provided which is set to be active when the humidity crosses a certain trip point. The circuit is mains operated and it is very easy to install. DHT11 is the humidity sensor used here.DHT11 is a ....etc

source code for interfacing humidity sensor with lpc2148

ABSTRACT

In this paper, we describe about the monitoring of Indian agriculture using LPC2148.Monitoring of Indian agriculture is
done using information of the temperature and humidity content. This is mainly used for saving water and monitoring agriculture without human presence. Temperature sensor and humidity sensor will continuously sense the information regarding the field. When the values are less than or greater than the threshold values it will do certain operations. We are usin ....etc
