8051 microcontroller based annunciator system

In any plant, when a process parameter goes to abnormal limit, the operator is to be alerted immediately, so that he can take corrective
actions to bring the parameter back to normal. Also, when the parameter returns to normal, the operator should know it. This task of calling the operator attention in such conditions is accomplished by alarm annunciation system. This function has a very important role in the safety of nuclear reactors and hence alarm annunciation system is classified as category-I ....etc

Are Soil Pollution Risks Established by Governments the Same as
Actual Risks



1. Introduction
There is an increasing use of risk-oriented policies to deal with the local effects of soil
pollution. The risks that such policies deal with are: human health risks and can also
include ecotoxicological risks. These risks are expressed in terms of negative effects and
chances between 0 and 1 that such negative effects will occur

Risks related to one soil pollutant
In prac ....etc

Meanwhile, Philip, with about 1,500 warriors, wandered over the land to arouse the savages to a general war of extermination. Then he made his way to the valley of the Connecticut, spreading destruction from Springfield, Mass., north to the Vermont line. Brookfield was fired, Deerfield burnt, and Hadley surprised, but at the last place the Indians were severely checked and repelled by the villagers under the leadership of Col.

voice ic apr9600 interface with pic microcontroller

ICStation team introduce you this APR9600 voice recording and playback system used in elevator based on the ICStation Mega2560 compatible with Arduino. It uses DC5V voltage to work. When you press the different keys, the loudspeaker will sound that which floor you arrive. This design uses a APR9600 voice chip as the core of the circuit and realizes the function of auto recording and playback. It uses power amplifier chip JRC286D to amplify the audio and enhance the volume. The voice recording ....etc
