Can anyone tell me what this device uses? Answered
Im really stuck at the moment. I've been racking my brains trying to figure out what sensor is used in this device and would love if someone could help me!
The device is this: http://www.ebay.ie/itm/NOVELTY-ELECTRONIC-PERSONAL-PROXIMITY-REMINDER-ALARM-/150412364558?pt=UK_Safety_Alarms&hash=item2305468b0e#ht_964wt_952
I've bought one but cannot for the life of me figure out what exact sensor it uses.
Thanks in advanced,
