IoT Greenhouse Monitoring System

Greenhouses require precise environmental control for optimal plant growth. An IoT Greenhouse Monitoring System tracks all critical parameters and automates climate control, creating the perfect environment for plants year-round.

Why This Project Is Popular

Protected cultivation is growing in India for high-value crops. This project teaches multiple sensor integration, automation, and environmental control - essential skills for modern horticulture and AgTech.

Project Ideas or Guide

Build comprehensive greenhouse automation:

• Temperature Control: DHT22 sensors track temperature and humidity. Trigger exhaust fans or misters when too hot.
• Light Monitoring: LDR sensor tracks sunlight. Activate grow lights when dark.
• Soil Moisture: Auto-irrigation when soil is dry.
• CO2 Monitoring: Add MH-Z19 for CO2 levels - important for photosynthesis.
• Automation: Auto-open vents, turn on fans, activate irrigation based on thresholds.
• Dashboard: Real-time monitoring and control via mobile app.

Components Used

• ESP32
• DHT22 Temperature/Humidity Sensor
• LDR (Light Dependent Resistor)
• Soil Moisture Sensor
• MH-Z19 CO2 Sensor
• Relay Module (4-8 channels)
• Servo Motors (for vents)

FAQ

Q: What plants can benefit from this?

A: Any greenhouse plants - vegetables, flowers, medicinal herbs.

Q: Can this work on solar power?

A: Yes, ESP32's low power consumption makes solar viable.
