The team built a compact device using: A soil moisture sensor An ESP8266 circuit board LED indicators and Telegram integration Based on the moisture readings, the device alerts users if the soil is dry — visually via LEDs and digitally via a Telegram message, making it timely and accessible. 

Idea: To create a smart, compact device that reminds individuals to water their potted plants by monitoring soil moisture levels. This project aligns with SDG 13: Climate Action and SDG 15: Life on Land, by promoting sustained greenery in everyday households. Constraints: The device must be waterproof to protect internal circuitry. It should be portable and easy to insert into any pot. It needs to be durable to withstand watering pressures. It must be aesthetically pleasing to blend with indoor décor. It should be self-standing in soil without additional support.
