- Data logging and Control
- Data logging
- -This allows you to record a series of measure-ments taken by sensors made during an investigation. They can measure:
- Temperature
- Light
- Sound
- Movement
- -The data can be recorded automatically, directly to a computer or you can log the data manually using a keyboard, mouse or mic for later use.
- Advantages:
- Data collection can be automatic.
- Readings can be taken over long periods.
- No chance of someone forgetting to take a reading.
- No human error.
- Sensors can be placed in any location.
- Readings can be taken quickly.
- Dis-advantages:
- If there is a fault it may go unnoticed for a long time.
- -This allows you to record a series of measure-ments taken by sensors made during an investigation. They can measure:
- Weather forecasting
- Some of the world's most powerful computers are used to accurately for forecast the weather. They are used to monitor:
- Change in average temperature of the Earth's surface.
- Ocean temperatures and currents.
- The movement of areas of high and low pressures.
- Paths of hurricanes.
- The data used to create readings of temperature, humidity etc. are collected from sensors such as:
- Weather stations
- Radar stations
- Satellites
- Weather balloons
- Aircraft
- Weather ships and buoys
- Some of the world's most powerful computers are used to accurately for forecast the weather. They are used to monitor:
- Micro-processor control
- Micro-processors are the heart of computers, carrying out many of the functions of the central processing unit (CPU). Some examples include:
- Central heating
- Fire alarms
- Dishwashers
- Microwaves
- Phones
- Consoles
- TVS
- Digital cameras
- Burglar alarms
- Washing machines
- DVD players
- Fridges
- MP3/4 players
- Remote control toys
