ESP32 Houseplant Monitor - Skips Watering When Rain Expected

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

Your houseplants need water, but not when a rainstorm is forecast to soak the city. This kit builds an ESP32-powered monitor that checks tomorrow's weather via an API, and only triggers irrigation through a relay-driven pump if no rain is expected and the soil is dry. It logs data to an SD card and shows status on an OLED display, all inside a waterproof enclosure.

What You'll Build

A self-contained weather-smart plant watering system. The ESP32 fetches a forecast via a weather API, reads three soil moisture sensors, and controls a pump through a 4-channel relay module. Rain prediction overrides soil moisture to skip watering, preventing overwatering. A DS3231 RTC stamps every logged event on a microSD card, and the OLED shows live sensor readings and the system's decision. You'll
