Monitoring & Measurement

Monitoring :-

Reading and accepting the data from a specific source ( sensor ) to the computer for a specific purpose eg. weather, medical or environmental...ect.

Measurement :-

Studying the data received from the sensor so a correct action can be taken upon it .

How does it work??

A sensor, such as a temperature sensor, can be connected to a computer. The computer can then monitor the signal from the sensor, reacting to changes, or it can record the data from the sensor at predefined time intervals.

Uses of these systems:-

1)Scientific experiments :- Many experiments can be set-up and left to run with a data-logging system measuring things like the temperature of a liquid, etc.
2) Weather stations :- Often these are placed in very remote areas to collect data about rainfall, temperature, wind-speed, wind-direction, etc. Data needs to be gathered all day, every day. This data can then be used by weather forecasters to help predict the weather over the coming days.
3) Environmental monitoring :- Scientists are very concerned about the effect that humans are having on the environment. Computer-based data-logging is often used to help gather evidence of these effects: the level of water in a dam, the speed of water flowing down a river, the amount of pollution in the air, etc.
