Electrical Conductivity of Live Snake Skin?

All I know is that they make great jumper wires. I plug the end into the power, and they bite down on whatever I'm pointing them at!!! Why resistance? If you want to make a snake warning device, why not create a sensor that is designed to particularly pick up serpentine motion. One thing about snakes, their movement is rather unique. They sure don't hop, skip, or jump. Vermin-

Don't know about your area of India, but any fair-sized Zoo should be willing to help out in non-invasive research. Ask for the senior herpetologist (they hate being called "snake guys"). They are usually willing to go to great lengths to raise public awareness of snakes. Practically, however, I don't see a great deal of utility in the idea. Short of complete perimiter sensors, snakes will get through. And don't forget small tunnels (as for rodents) and trees. Neat concept though, keep us posted.

First, if you can put in enough wires to sense any snake's entry point, you could block that entry instead. Second,while it only shows a single snake, here is evidence that they CAN conduct electricity. And it's in an apparently dry area. http://www.bushveld.co.za/pictures-python.htm

Have you thought of creating a combination motion and temperature sensor. Most are commercially available. Since Most snakes can only be fully active if their body temperature measures between 68 and 95 °F (20 and 35 °C) You should be able to distinguish snakes from other warm blooded critters

It would have to be a pretty sensitive sensor as I don't think a snake's temperature deviates greatly from the ambient temperature.

What about using capacitive sensing, just like what is used on touch screens. A capacitive strip along any potential entry paths would be set off by anything coming in contact with it with a certain amount of pressure. A mouse or rat may get through by not touching the strip, but since a snake can't avoid being on the ground, it must travel over the strip to gain entry. Then just set off an alarm to indicate something has passed over.

Something like this.

This other company helped to develop the technology in the beginning. Although they are focused on the big market, namely laptop computer touch pads, they may be interested in colaborating with you on a specialty device such as yours. They also provide (sell?) developer kits so that you could prove the concept.

This is a good idea. With a proper time delay filter, it seems more pratical than conductivity method.
