ESP32 Automatic Plant monitoring with Google Home

An Internet of Things (IoT) project demonstrating an automatic plant monitoring and irrigation system built around the ESP32 microcontroller. The system utilizes a capacitive soil moisture sensor to continuously measure soil conditions. Based on user-defined moisture limits, the ESP32 automatically controls a water pump via a relay module to maintain optimal soil hydration levels.

The project is integrated with ESP RainMaker, which eliminates the need for custom mobile application development or dedicated backend servers. This setup allows for remote control and monitoring of the system through the RainMaker application or via voice commands using platforms like Google Assistant and Amazon Alexa. Users retain the ability to switch to a manual mode for direct, remote pump operation outside of the automatic cycle.

This short informative video details the construction and functionality of this DIY smart irrigation solution, suitable for beginners interested in home automation and embedded systems projects.
