PEST GUARD
Offline Pest ID & Pesticide Recommendations
PestGuard – an offline mobile application for iOS and Android that uses AI-powered object detection to identify pests and recommend effective pesticides, helping users protect crops and homes from pest damage.

About the Project
The client required a robust mobile solution that could work in offline environments, particularly for use in rural areas with limited internet access. The goal was to develop an app that allows users to identify pests using their smartphone cameras and recommend suitable pesticides based on the identified pest.
Additionally, the app would inform users where the recommended pesticide can be purchased. Synec partnered with the client to build a machine learning-powered app using object detection to identify pests with high accuracy. By implementing an intuitive recommendation system, the app assists farmers, gardeners, and household users in controlling pests effectively while functioning offline.

Features
Pest Identification via Camera with AI Object Detection
The core functionality of the app lies in its CNN-based Single Shot MultiBox Detector (SSD) model, which uses the phone’s camera to identify pests in real time. Users can scan an insect or pest, and the app quickly detects and classifies the pest using a trained object detection model. The detection process provides high accuracy even in low-light or challenging conditions.
Pesticide Recommendation System
After identifying the pest, the app recommends the most effective pesticide for eliminating the specific pest. Each recommendation comes with details about the pesticide, including active ingredients, application methods, and usage instructions. The system ensures that the pesticide recommendations are targeted and safe for both crops and the environment.
Offline Functionality
The app works completely offline, allowing users in rural areas without internet connectivity to still utilize its full features. All pest identification models and pesticide databases are stored locally on the device, ensuring that users can identify pests and receive recommendations even in the most remote locations.
