IoT Smart Compost Management System

Composting is becoming popular for organic waste management in homes, farms, and communities. A Smart Compost Monitoring System tracks critical parameters like temperature, moisture, and pH, helping optimize the composting process for faster and better-quality compost.

Why This Project Is Popular

Organic farming and waste management are growing in India. This project teaches soil/farm sensor interfacing, automation, and IoT for agriculture - highly relevant skills for modern farming. It's practical for home gardeners, organic farmers, and community composting operations.

Project Ideas or Guide

Build these smart composting features:

• Temperature Monitoring: Use DS18B20 waterproof sensor to track compost temperature (indicates microbial activity).
• Moisture Sensing: Soil moisture sensor tracks water content - compost needs 40-60% moisture.
• pH Measurement: pH sensor ensures optimal acidity (6-7.5 pH ideal).
• Auto Turning Alert: Alert when temperature drops - indicates need to turn compost for aeration.
• Dashboard: View all parameters and trends on IoT dashboard.

Components Used

• ESP32 / Arduino
• DS18B20 Temperature Sensor
• Soil Moisture Sensor
• pH Sensor (SKU:SEN0161)
• OLED Display
• Relay (for pump/sprinkler)

FAQ

Q: How does temperature indicate compost health?

A: Active composting generates heat (45-65°C). Temperature drop means microbes are less active.

Q: Can I automate watering?

A: Yes, connect a water pump via relay that activates when moisture drops below threshold.
