Object Speed Counting in sunlight.
Mike Chaloupka email (remove spam text)
I have been monitoring mail traffic for IIR, Laser diode or Ultrasonic suggestions that my be able to solve my problem.
I need to detect the speed of an object 2 - 5 feet from the sensor mount.
Sensor is mounted upward looking at the sky.
My thought was to use two ultrasonic sensors to detect a pulse width to determine the time the object was within the cone.
Range data is secondary if at all.
Need to be inexpensive - doesn't it all....
Suggestions / contacts are greatly appreciated...
