The question is not so trivial. I mean not only the variable to measure and how to measure. But also I am asking which type of sensor, which sensibility, etc.
For example if a wasp is flying in this forest on the trees and comes next to my sensor how will I detect which kind of insect is it ? I can use an acoustic detector ? An ultrasonic sound detector ? And what about its shape ? Can I use a low cost image sensor ? Which one ?
The ultrasonic sensor can be used for the presence of an object in air. But the size of objects are limited due to wavelength and also the distance from sensor.
In my opinion a fast high resolution camera could be utilised. The image processing may be used with reference to the previous image of that particular insect. The shape and colour may used as the base for the detection.
Hi;
Pseudo-acoustic optical sensors can produce high quality data; that additional functionalities, both intrinsic and extrinsic to insect behaviour, can be exploited to improve insect classification.
With my best regards
Perhaps passive acoustic/ultrasonic sensor and deep learning, as used in language processing/Alexa etc to identify the insect ? Also, ultrasonic doppler where the wing beats modulate the doppler. I believe the wing beat frequency depends on the species.
