	Data Logging
		Data logging is used to capture an arbitrary amount of S Meter data and save it in a file.
		When the program is running, the S Meter data is always being collected from the radio at a rate of 20 samples per second.
		In this case, logged data is never written to the file at a rate greater than one record per second, and the amount of data written is a single line of text.

	Data logging - Wikipedia, the free encyclopedia
		Data logging is the practice of recording sequential data, often chronologically.
		To log is a verbed derivative of the noun logbook; the verb form means to record in a logbook, and may have been coined in the 1820s.
		In computerized data logging, a computer program may automatically record events in a certain scope in order to provide an audit trail that can be used to diagnose problems.

	Data Logging
		Data logging equipment therefore often has to be very robust so that it can resist extremes of temperature or radiation for example.
		Data logging equipment can record the movement and software can then plot it against time on a computer screen and store it for further analysis.
		In an experiment during the last UK eclipse, light sensors and temperature sensors were used to continuously recorded the light intensity, the temperature in the sunlight and the temperature in the shade.

	Lesson 7: Data logging application
		Since the write speed is slower than the maximum data generation of the mote, it is the logger component that effectively limits the capture rate.
		The write speed is proportional to the amount of data being written, but after every log entry write there is a pause of about 5 ms.
		For the LOGGER in the release, we chose log entries of 16 bytes, as a reasonable compromise between logging performance, buffering requirements, and interactions between the logging components and the messaging subsystem.
