Datalogging
Datalogging is the process of taking data from a sensor or a group of sensors over time and storing it for later use. Factors that influence how you datalog are:
- resolution of the sensor - how many bits or bytes of data can the sensor report? You'll need that much memory for every reading
- time resolution - how often do you need to record the data?
- latency - what parts of the system cause delay between reading the sensor and saving its value?
