To avoid public transport and the car, I decided to go to work on foot everyday but I have to pass a small, but dark (in the evening) and scaring wood.
Even if I use flashlights, I'd like to have a kind a "life scanner", like the one used by Predator vs Alien to detect alive (hot/moving) creatures.
Beside the sci fiction side of the question, I was wondering if PIR can be used while moving, so that I can mount on my backpack and control it with an arduino while I'm walking.
If it's not possible, do you have any other ideas?
What I need it's just a way to know if there are alive, enough big to be scaring, creatures in the wilderness around me (for not alive creatures we will discuss later).
Has pointed out, a good alternative can be an Infrared camera, there are some good tutorial and Howtos in the Net.
I don't need a detailed image, but just to know if and (more or less) where there are alive creatures (hot blood animals?), as an image sometime is better then 1000 words:
As it has been pointed out, is this feasible or it's just sci-fiction?
Thermographic cameras exists and are widely used: http://en.wikipedia.org/wiki/Thermographic_camera
I found a solution here http://www.embedds.com/interactive-diy-infrared-and-ultrasonic-scanner/ , but the range is really small (21 inches = 0.5 meters)
This is another way to create a "radar" starting from a home made thermographic camera.
