Green House & Air Quality Monitoring System

Abstract

The rapid development of smart agriculture technology has improved the efficiency of greenhouse farming. In the project, an ESP32-based smart greenhouse monitoring system has been designed, which can control the environment in the greenhouse automatically. The system uses DHT22 sensors to monitor the temperature, humidity, and moisture of the soil, which are the most suitable conditions for the growth of plants. In addition, a fire sensor has been integrated into the system, which can monitor the hazards in the greenhouse, ensuring the safety of the plants. The data from the sensors are processed by the ESP32, which compares the data with the set parameters to make intelligent decisions. The system can automatically turn on the relay-based cooling fan when the temperature rises above the set limit. The system is economical, as it uses a 7V battery, and can be implemented efficiently.
