** --> ** Now write a class CsvWriter that reads readings from one of these sensors at a given time interval and writes them to a file. (File name, interval and sensor should be configurable).
- Tip: Create an object of a child class of Sensor and pass it to the constructor of CsvWriter as a parameter together with the interval and the filename.
File format: each line is Comma Separated Value (CSV) i.e. something like _time stamp_,_name of sensor_,_unit_,_measurement_. Each line corresponds to one measurement.
- Implement a method "public void run()" which you then call to actually take the measurements and write them to the file.
