Introduction
๏The early detection of crop insects is an
important aspect of crop protection and can
help farmers minimize crop damage and
maximize crop yields.
๏About 20-25% of crop yield is lost due to insect
attack
๏ Every insect sound has a unique set of
frequencies which can be used to train the
Tiny ML model

Problem Statement
Lack of early detection leads to the
following problems
๏Crop Damage and Loss.
๏Overuse of insecticides leads to soil
infertility
So the major problem is that a large
portion of a crop yield is lost due to insect
infestation which needs to be tackled using
modern technology

Objective
The objectives of the project are as
follows:
๏To develop a ML model for early
detection of insect infestation using
audio signal
๏To deploy the model developed in
hardware
๏To test the working of the hardware
model for various insect sounds

Data Processing
Preparation of dataset
๏ A Dataset comprising of audio files in a
format compatible for our ML model has
been created.
๏ The dataset contains audio files of
insect sounds of 3 seconds duration.
๏ All audio signals are sampled at 16 kHz
dataset to make the model more
accurate and to reduce the complexity.

Data Processing
Creation of spectrogram
๏ We use spectrum of frequencies of a signal
as it varies with time.
๏ They can be used to identify specific features
of the audio signal, such as the presence of
certain frequencies or patterns over time.

Data Processing
Splitting of dataset
The dataset is divided into 3 subsets
Each subset is used to train the following process
๏ Training (60%)
๏ Validating (20%)
๏ Testing (20%)

Data Augmentation
Data augmentation is a set of techniques used to
increase the size of a dataset.
๏ Adding white noise to the audio samples
๏ Adding random silence to the audio
๏ Mixing two audio samples together
