As far as I understand proximity sensor in mobile phones works on a principle there is an emmitted IR coming out FROM proximity sensor and reflected IR comming TO proximity sensor. Is there any method how I can measure the emmited IR coming FROM the proximity sensor?
Thank you for reply
Google "mobile phone proximity sensor". There appears to be no IR sent out. As the phone is brought close to your face it is sensed by various means including capacitance and IR emitted from your face.
