Build a Smart Garden with ESP32 Under !

Thinking IoT is only about smart homes? Think again — ESP32 can power your own smart garden!

What You Need

• ESP32 DevKit (~)
• Capacitive Soil Moisture Sensor
• DHT22 Temp & Humidity Sensor
• 2-Channel Relay Module
• 5V Water Pump
• Small water container

How to Build

1. Wire the soil moisture sensor to ESP32 GPIO
2. Connect relay to control the water pump
3. Code in Arduino IDE using WiFi + Blynk libraries
4. Set auto-watering trigger at <40% moisture

Best Part

Saves water! Auto-watering when you're away — no more dead plants.
