Abstract
This study presents the design, development, and evaluation of an automated greenhouse climate control system using a DHT11 temperature and humidity sensor integrated with an ESP32 microcontroller. The system addresses the limitations of manual environmental monitoring in small-scale greenhouse applications by providing continuous, real-time sensing and automated regulation of critical environmental parameters. Temperature and humidity significantly influence plant growth, and unstabl vbce conditions may result in plant stress, reduced growth efficiency, and lower yields.
