Hi,
I use a Raspberry pi 3B and the applcation RPI_Cam_Web_Interface for building a birds survey system.
My system works, but the motion detection is done by checking differences between several images. Then that is not good when there are trees or leafs moving.
Then I want to use a PIR Sensor for motion detection.
I currently tried with a HC-S501 PIR but I encounter too many issues with it. Instead of staying stable, it continuously detects motion, and it seems that this is due to disturbances created b Wifi or electronic environmenet.
Then I’d like to use another PIR sensor which could be more stable.
I was told to try an AM312 PIR, but it seems that it will not be sensitive enough for birds detection.
Do you have a recommendation for a PIR sensor whicjh could do the job correctly ?
Man thanks in advance.
I think SONAR sensor HCSR04 will be a better choice for your application.
Hi,
Thanks for this idea.
However, the SONAR sensor checks distance from a subjets to the sensor. Then, how to use it for only a motion detection ? I don’t know if the subject will be at 1 meter or a 20 cm.

Hello @pdemeure!
As you are already using a Raspberry Pi and a camera I think a good solution would be to use object detection. I know it might sound difficult but there are lots of open-source projects available and even the most popular pre-trained models already include birds, for example YOLO.
Or you could even try to find a model specifically trained for birds:

Or if you are familiar with OpenCV you could try that route as well
I hope that helps!
