I am looking at making the reverse of a motion alarm. I need a no motion alarm. I will be watching a slowish moving machine. If it stops moving for 3 seconds or detects a fire, it kills power to the machine via a relay, sets off a buzzer (that I can turn off), turns on an led, and possibly notify me some how (not essential but would be cool).
I am not 100% sure what is the best way to go about watching for motion. I was trying to avoid putting anything on the machine if I can. If not it can be done just will have have to run 5 or 6’ of cable. What would be the best but still fairly simple Pir, ultrasonic, accelerometer, vibration? I am only looking for movement primary and flame secondary.
I was having a hard time figuring out the software because it is missing so many basic parts. I get that several will probably be identical to something in there but would make it so much easier for people new to the program.
Thanks for any help
