Hi,
I am trying to create a sensing device that can determine if a person is wearing a hard hat or not. This would be embedded into the hard hat itself.
I am thinking either a pressure sensor (FSR) or a capacitive proximity sensor that is imbedded in the rim of the hat (the part which sits on a the persons head). My main concerns are that I read FSR's will be damaged if pressure is applied for a longer time period (which would be the case here). Also, the capacitive sensors are very sensitive to environmental factors — humidity in coastal/water climates can affect sensing output, so they may not be robust enough.
Does anyone have experience with either of these sensing techniques and could provide a recommendation for this application?
Thanks a lot!!!
