Many plants die because we forget to water them or don’t monitor environmental conditions. This project creates a smart plant watering system that automatically waters the plant when the soil is dry, measures temperature and humidity using a DHT sensor, and displays all data on a 16x2 LCD. Additionally, the system connects to a Blynk app on a mobile phone, allowing real-time monitoring and manual control of the water pump.
The project uses an ESP32 microcontroller to read sensors, control a relay for the water pump, and communicate with the mobile app. It’s fully IoT-enabled, teaches basic electronics and coding, and is expandable for multiple plants or additional features like notifications.
