I want to create a device that triggers a sound alarm if it senses human presence (not motion but actual presence), and can be programmed to activate at only certain times of day on certain days of the week. eventually i want to have more options, like having “x” amount of minutes grace period before it triggers during the active time of day. just to name one.
How do i make this?? or, to save a LOT of time…does this already exist?
The D6T44L06 looks like a good place to start…but I have zero engineering/electrical experience
Thanks in advance!
Educational sites with videos that you can point me to would be great as well
