RE: MULTIPLE USERS AUTOMATIC HAND SANITIZING MACHINE

Another great job. Your projects are amazing.

I have a few questions/requests, though:

  1. I am interested on how did/would you strategically place the IR sensors. Ideally, I would place them beside the spout to detect the hands on the right spot. However, there is so little space to attach them. Did you place them somewhere else?
  2. Since you are using IR sensors, I am also interested on how can you protect the system from ambient or external IR sources (e.g. the Sun). What kind of IR sensors did you or will be used?

I would appreciate it very much if I would get some clarity. 🙂

Thank you again for making such very useful projects and sharing with us.
!1UP.

First of all this machine is design to be indoor where the level of ambient light is low so that our infrared sensor can work properly.
Secondly the infrared detect the user presences not his hand.I did this by locating the sensor underneath the kitchen sink where is expected for him/her to stay.
Thirdly along my way to deliver this awesome project we had an accident thank God I was preserved. Well done
