LoRa based Plant Monitoring System

Smart Poultry Brooding System (ESP32 + DS18B20 + OLED)
Excited to share my latest IoT-based funding project!

This system is designed to automatically control the temperature inside a poultry brooder using real-time data from a DS18B20 sensor, helping farmers maintain ideal conditions for chicks.

Key Features:
🔹 Real-time temperature display on OLED screen
🔹 Automatic relay control for heater & cooling fan
🔹 Intelligent temperature threshold system (default: 45°C)
🔹 Fault detection & error alerts for safety
🔹 Built using ESP32, DS18B20, and Adafruit SSD1306 OLED
Project Type: Research & Development – Funding Project
Objective: To develop a low-cost smart poultry management system for sustainable and efficient brooding, especially for small and rural farms.

🐣 This innovation aims to minimize manual monitoring, improve chick survival rates, and reduce energy waste.
