Insect detecting sensor.

Hi Aryaman,

I can't find any off the shelf insect detecting sensors any where. I really don't think such thing exists.

Small sized moving objects can be detected using a laser and a photo diode. But this set up doesn't give guarantee that it only detects the insects. Circuit will alarm you when the photons emitted from the laser is not landing on the Photo Detector.

If you want to make sure that the system detected an insect then you need to provide some intelligence to the system. Normal cameras wont work because insects are hard to get focused. May be  wing flapping sound can be detected using a sensitive microphone and it can be used to identify the insect.

But generally insects killers works by attracting them to a trap. Considering the insects size this gives more accuracy. Keeping the detector somewhere in the room reduces the probability of detection.

I have got an idea!

All insects got wings! If you can sample the data at the photo detector at higher rates, we can detect the laser beam getting cut due to the wing flapping. There by you can confirm some flying insect has detected. Also make a Laser-PD ring to increase the chance of getting the insect detected.

use the link john shared as the reference.

But as Jan suggested it's an idea for the next design challenge.

Aswin

thank you sir for your response and all others who have responded .

Actually I was working on a science project , in which I am trying to design a low cost Agricultural drone , since they are very costly and farmers of my country can't afford it and my country India is a Agricultural country , so we need it a lot .

And this year we are getting a lots of minus points in the field of agriculture , so I was trying to design it to help my country men .I was almost done , it can spray fertilizers spray seeds and everything but the problem came when I started thinking about pest killing program in low cost . without it , it's incomplete .

it's very depressing to hear that it's not possible .

but anyway thanks for your response .
