Being a novice at data collection and manipulation I am looking for a simple (PC-Based?) event recorder. I have a sensor that provides a simple NO or NC contact output. I would like to be able to record each (real) time moment the switch is operated and the duration it remains operated - all over a 24 hour period. I have a feeling that there are some existing options to do this but am too inexperienced to find one. Any suggestions would be greatly appreciated - I am very willing to learn.
