Datalogger that reads temperature, humidity and light level every 10 seconds, and store the data in a microSD card (.CSV file).

Dependencies:   DS1302 SDFileSystem mbed

This is a weather station/datalogger using a Freescale FRDM-K64F dev board, a LM35 (temperature sensor), a DHT11 (temperature and humidity sensor), a DS1302 (timekeeper module) and a LDR (light level sensor). All the data is periodically stored on a microSDHC card; The acquisition period is adjustable via software (by setting the value of a counter).

There is also (commented) code for sending all these information via serial to a terminal on PC.
