Portable Data Logger

A data logger is an electronic device that records data provided by measuring instruments or sensors. It is an invaluable tool in various fields and industries. In the past, people relied on chart recording for keeping track of data. This method was prone to human error and handling large amount data also require more manpower. The electronic data logger is more precise and can perform its task remotely or without human intervention. The data logger serves several purposes. It is used for maintenance and for performing troubleshooting of industrial equipment. It helps keep places of work safe and for maintaining efficiency of operations. The portable data logger is small in size and is used outdoors and in applications that requires a frequent changing of location. One big advantage of this type of data logger is that it allows remote collection of data. An example is the gathering of weather data such as temperature, rainfall and humidity for a certain area. Instead of having a person manually recording changes of these conditions, a data logging device can be activated and left unattended while it gathers data for a significant amount of time. A portable data logger is primarily composed of a microprocessor, internal memory, sensors and a battery. The microprocessor makes it possible to program the device. The internal memory stores the collected data. The data from the memory can also be transferred to another device such as computer for further processing. Sensors are instruments that acquire data. Some examples are temperature, wind speed, and pressure sensors. The battery powers the device. A battery with a larger power capacity allows the data logger to record data for longer periods. Modern data loggers have interface that makes it even easier to use.
