REFLECTION DATA LOGGER

REFLECTION DATA LOGGER

This is not by first time I am using data logger in the class. Before this I have used it when doing physic experiment while I am taking physic course before. What is data logger? A data logger is an electronic device that records data over time or in relation to location either with a built in instrumental sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.

Using data logger will give us more benefit compare when we doing it manually. One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis. Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period. This allows for a comprehensive, accurate picture of the environmental conditions being monitored, such as air temperature and relative humidity.

There are many applications using data logger nowadays because it helps our daily life become more systematic. The example of application using data logger are unattended weather station recording (such as wind speed / direction, temperature, relative humidity, solar radiation), unattended hydrographic recording (such as water level, water depth, water flow, water pH, water conductivity), unattended soil moisture level recording, road traffic counting, measure temperatures (humidity, etc) of perishables during shipments: Process monitoring to verify warranty conditions, deformation of any object with geodetic or geotechnical sensors controlled by an automatic deformation monitoring system and many more.
