Hi.
The last few weeks i'm trying to build a reaction meter , and so far i tried to use capacitive sensors to track the presence of a hand to turn on or off the time counter.
The "system" works very well but i belive that the response time of this kind of sensor is not accurate enough.
Could you please make any suggestions on what is the best sensor for my case of use ?
The only "rule" that this sensor must follow is to avoid any physical touch with the human body and of course better responce time than the capacitive sensor
Thank you in advance
