Good afternoon, my fyp title is Green light and portable lizard trapper. Is it possible to design a circuit that using sensor without coding by using IR sensor to generate an electric shock. And how the design of circuit need to be conduct? My idea is to make a hardware which turn on by DC supply like battery, and use LED to attract insect hence attract lizard. When Lizard trap into the device, then the IR sensor sense the lizard, then the whole circuit start to run and generate electric shock to kill the lizard. is it possible?

A couple of things:
- You wouldn't easily be able to tell whether it's a lizard in the trap, or some other animal/person's hand/etc.
- Why would you want a kill a lizard?
-
sometime it is because of the hygiene problem , and lizard sometime brings the virus that is harmful t the baby health. So is it possible for me to use a sensor without using coding? or do you have any suggestion?
-
Just catch the lizard on a piece of paper or in a cup and put the poor thing outside?
I'm not sure babies catching viruses from lizards is a big issue.
-
so do you know any sensor that can be used to sense the lizard without using coding?
-
How big are the lizards? I'd think common mechanical devices would be available and much simpler.
-
It seems to me that a lizard trap would likely be very similar to a mouse or rat trap. If I were you I would just search for a better mouse trap.
Also, electricity isn't a good idea for any kind of trap, especially if there are children (or grownups for that matter) around.
Electric shock causes involuntary muscle constriction that could easily cause serious injury or death to people or pets.
Some lizards, such as monitor lizards (such as the Komodo Dragon https://en.wikipedia.org/wiki/Komodo_dragon (https://en.wikipedia.org/wiki/Komodo_dragon) from Indonesia) can be aggressive and quite dangerous when grown up. They are carnivorous, and may eat up to 80% of their own body weight in one meal.

For a Komodo dragon you could put a crocodile trap in your lounge room and bait it with half a sheep.

I think he's talking about those little geckos that crawl all over your walls. They're pretty harmless, you don't need to fry the cute little critters, just trap them in a funnel trap or something like that and dump them outside. The bigger question is how they're getting inside, try sealing up cracks and things, before you get something worse creeping in like rats.

If I remember my biology correctly lizards are cold blooded ie thier body temperture is at or near ambient. An IR sensor might not work all that well by itself. Maybe with an IR LED and breaking a beam might work. What is the visible range of these creatures? Can they se into the IR spectrum?

just a small gecko

One family in Thailand keeps a crocodile "Kheng" as a family pet!

It would never hurt them, it's never killed anything.

I know a sensor that does not require coding that will probably deal with you issue.

Do you really want to deal with the smell of electrically cooked lizards? Wouldn't it be easier to use a glue trap or even a non-lethal trap they crawl into and can't get out?
-
what is that sensor?

It's a cat

Glue traps are inhumane. Don't use them.

I have two cats. Since I got them I never see a gecko any more. They finished them all. Before every wall used to have one at least. I miss them a bit.

Glue traps are inhumane. Don't use them.
Less humane than using electricity to potentially slowly cook them to death?
A cat has always been my preferred method of pest control. They make good company too.

Had a pair of geckos doing the old bit of making out one day, on the pole of the electric fence. The guy had his tail touch the live wire, and the lady was the ground as she had all feet hanging on to the grounded steel post. As he tripped the fence they went out with quite a bang, were still twitching with the pulses when I came out 20 minutes later to find what was triggering the fence.

When you are afraid of viruses and similar, a cat is not such a good idea. Cats do spread viruses and other nasty stuff - likely more than lizards. Usually not many viruses effect mammals and cold blooded lizards. It might even help to have a few geckos to reduce the insects - which are more likely to cause trouble.
When I was in the US, they liked to have a rattle snake around to keep away the mice, as some mice where spreading a very nasty virus. A different type of snake would be OK too.

Once it's pointed out, the solution's obvious! :D

No lizards here but we get racoons, squirrels and chipmunks. The experts say that possums are coming and will take over from the racoons. I saw one possum on my fence. There are deer in the forests.
I have never seen a rat but I saw a couple of mice far from my home. No snakes and no lions. The signs say there are coyotes in the parks at night but I have never seen one.

In the islands where Komodo dragons still live alongside humans they periodically sacrifice a live goat or deer to the dragons. An ancient ritual.
Similar to the "Wicker Man" in the UK.

I've never heard of cats spreading viruses, I've had cats my whole life and never had any trouble with it. Mine are indoor-only now though, they live a lot longer that way. As far as animals go cats are quite clean, certainly less germy than (human) kids. My friends with kids are always getting sick, especially around the start of a new school year.

Toxoplasmosis? A huge percentage of humans are infected too. (a third globally)
It changes people's brains. They usually are not aware they have it unless they get something like AIDS or some other systemic infection that suppresses their immune systems and then it can be really dangerous.
Things like that may not kill you but they certainly can change peoples lives for the worst. At the very least if you live in countries without free public health care having it in your MIB file might make you uninsurable soon.
Which could mean unemployable too.
-
That's one I hadn't heard of, although looking it up apparently the most common method of spreading is through food, with infected cat feces being next on the list. I can't speak for everyone but I try to never contact any sort of feces. Rats, something typically kept under control by cats are known to spread Hantavirus, and given a choice between the two it sounds worse.
Children still seem to be a far greater risk of exposure to all manner of viruses and bacteria than animals typically had as pets.

Fact is that if it's not one thing then another will come along thats equally as obnoxious to us humans and indeed to all living creatures. The only things that will win in the end are insects, as we and animals die, its insects who get the last laugh because they will feast on our bodies and recycle them unless we are cremated, the insects will get us all sooner or later.
