I want to have two sensors, one on the inside of my door and one on the outside so when I walk in my light turns on and when I walk out the light will turn off, how would I go about doing this?
I don't have much time to talk. (Or...type.) But I can tell you that what you want is an infrared motion detector. I even found one that can sense which way you are walking. :shock: Right here: https://www.electro-tech-online.com/custompdfs/2003/11/GLDIR1.pdf Check it out and tell me what you think. :wink:
