#113752 - Sensor Responding to: ???'s previous message |
Is your sensor a beam break setup or is it looking for a specific reflection of ambient light from the chrome bumper? If the latter, what is going to prevent another bright spot on the car from falsely generating an impulse? What happens if the chrome is covered with mud or dirt? What happens at night? Since you are dealing with vehicular motion, what safety measures have you considered? Is life, limb, or property dependant on this circuit? (I dearly pray it is not!)
