Why is an analog eyeblink sensor better than a digital eyeblink sensor? Currently, most eye blink sensors on the market are digital. they can only distinguish between the eye being fully closed or fully open, unable to detect partial blinks or quick blinks. However, the analog sensor provides waveforms. By analyzing analog values, you can detect full...
