Build a Smart Greenhouse Climate and Soil Manager with Arduino Uno & DHT22

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a greenhouse that breathes on its own — venting excess heat, turning on a fan when humidity spikes, and watering only when the soil is dry. This advanced kit lets you build that intelligence, combining sensor data from the DHT22 and dual soil moisture probes with automated relay control. Perfect for serious plant enthusiasts, agricultural engineering students, and anyone exploring precision horticulture.

What You'll Build

A fully functional greenhouse automation system that reads real-time air temperature, humidity, and soil moisture on a 16x2 LCD. When conditions exceed thresholds, it opens servo vents, switches on an exhaust fan, and activates a water pump — all automatically. You'll have a prototype that mirrors real-world smart farming equipment.

What You'll Learn

• Interfacing multiple sensors (DHT22, soil moisture) with Arduino Uno and reading accurate environmental data
• Writing conditional automation logic with threshold-based triggers for relays and servos
• Controlling physical actuators — servo-driven vents, fan, and pump — using a 4-channel relay module
• Integrating an I2C LCD backpack to display sensor values in real time
