I need to sit in line with my truck. I want to be able to close my eyes for a min., but I need to know when the truck in front of me moves.
I think I want to use a ultrasonic sensor 0-25 ft #2157351 from Jameco with something like a DC 3-24 V Electronic Tone Buzzer Alarm 95 dB.
It would be nice if I could make a box and put on the dash of my truck. When I pull into line I would just flip a switch and close my eyes. When the alarm goes off I turn off the box and pull ahead.
Will this ultrasonic sensor work through my windshield?
I think I am building a motion sensor, only in reverse. I want to sense something when it leaves my sensor area, not when it come into it. Can it be done?
Cheers.
