Hello fellow humans,
Excuse the simplicity of this question. What I'm looking for is ancient technology, but I have a lot of learning to catch up on. Based on the following details, could you please suggest what sensor (model number preferably) I'm looking for?
1. Detect movement of one of the following 'Objects': 1) " diameter by 1" high hard black rubber 'disk' (speed: 20-170kph), 2) person running by the sensor (assume feet are always on the ground) (5-30kph), and 3) the swipe of a hand (not sure the speed of a typical hand swipe).
2. Movement simply means presence of one of the objects in front of the sensor. If you know of a sensor that can detect speed as well that would be interesting, but not necessary.
3. It's preferred that the sensor doesn't require a reflector or a 2-part system, but it's not out of the question if that's the best option for cost and reliability.
4. The device that the sensors will be used in is the shape of an Apple TV box. The idea is to put sensors on the 4 sides, for detection of all 3 Objects, and one on the top, only for the hand swipe.
5. Use in dark or light environments is preferred, but if only one is an option, then it would be light environments (gym lighting or daylight).
6. The temperature range of the Objects is -20 to 40 degrees.
7. The sensor detection range should be a minimum of 2 meters for the 4 side sensors. Up to 3m is fine, but not necessary. The top sensor, which is just used for the hand swipe could be 1m, if that means using a cheaper sensor.
8. Within 0.2 seconds reaction time is ideal.
Minimum Application:
Detect the presence of an Object when it crosses a plane. Reliability is paramount.
Note:
A normal cheap IR sensor that we tried barely senses 50cm, so that's why I'm looking for a specific model number, if you're aware of something.
If I missed any detail, please let me know! I will happily get into a deeper discussion. Thank you in advance for sharing your knowledge.
Wish you a happy and peaceful day.
