alarm sensors with cats
Hi,
I bought couple of motion sensors long ago. I installed one at the entrance space of home. I have 2 cats at home. Yesterday night I turned those motion sensors on to detect intrusion.Problem is that my cats lives outside the rooms, they move from roof to downstairs and even go outside the home and come back.Even other cats come to my cats place to eat their cat food. My sensor detects the cat as intrusion and turned on the siren at full volume at night, disturbing us and our neighbours. I was thinking if there's solution to this problem that I can do with it, because I can't control the Cats, even if I keep my cats inside the home in rooms, then other cats have developed the bad habit of coming to my home to eat cat food, they never use to come before, they now start visiting my home when they see I put cat food in home, easily accesible to them, so few other cats visits my home. I first observed how the sensor works. It has a one red LED in the sensor, If I'm not wrong they are infra red sensors, I'll double check it when I reach home.Whenever the sensor detects something, the LED gets on and simulatenously the siren gets on. LED lits for 2-3 sec and then it turns off. Suppose if I walk in it's path. The motion detector will detect me and lit it LED along with siren. If I remain still over there and don't move a muscle. It gets off. If I move a little bit from that position it detect me again. I was thinking that I should make an electronic circuit that would count how many times a motion detector detects an object in specified time period, then triggers it up. If somebody is moving in it's path,and if detector sensed it 2-3 times within 5 sec, it triggers on the alaram. If cat walks within that area, the sensor detects it just around 1-2 times within 5 sec and not more than that. So, I think that a counter would be use, which counts the number of registered intrusion within a time. At around 5 sec, the timer would reset the counter. If counter reach value of 2-3, then it triggers on the alarm. It means a lot of movement is done in the resctricted alert area, that much movement is not done with cats.Please share your view on it.
