Data Logging, Weather and Control Systems

Data Logging, Weather and Control Systems

1. Data Logging

   • Readings are taken regularly over a period of time by using sensors
   • Readings are taken automatically
   • The logging period can be changed
   • Sensors can be moved into different locations
   • Data can be sent to a computer and processed
   • The data is analysed, then becomes information
   • Readings taken 24/7
   • Readings are taken faster
   • The system never forgets to take readings
   • No human error when taking readings
   • Does not need a person to take readings
   • Can be used in inhospitable locations, such as the North Pole
   • Multiple readings can be taken simultaneously
   • It is expensive
   • Equipment malfunctions can cause incorrect readings.

2. Sensors

   • Used to detect and measure physical quantities
   • Heat
   • Light
   • Sound
   • Pressure
   • Movement
   • Humidity/Moisture

3. Weather Forecasting Systems

   • Data collected by sensors then sent to a computer to be analysed
   • Heat
   • Rainfall
   • Pressure
   • Wind speed
