Soil moisture sensor - ESP32

Soil Moisture Monitoring with ESP32 and Hygrometer Sensor I took the battery compartment from this project. (https://makerworld.com/en/models/539919-18650-battery-case-21700-battery-case#profileId-467576) Project Description This project uses an ESP32 and a soil moisture sensor to monitor the soil’s humidity levels and send updates to a Telegram bot. The system is designed to optimize power consumption while ensuring reliable measurements over time. The sensor is powered only when needed to prevent false readings and reduce battery consumption. Additionally, the ESP32 enters deep sleep between measurements to maximize battery life.
