 Greenhouse Monitoring System



 🔍 About the project 



A simple greenhouse monitoring system made with ESP32. The system detects possible risks for plants, such as: temperature, humidity and light. The 

user will be warned whenever one of the conditions is inappropriate. The system also sends the data to a full stack application via an MQTT connection.



 🔮 Technologies Used 





  

    

  




 💻 Website 


The website displays a table that breaks down the data received by the system, updating its value in real time. To improve scalability, the table will grow dynamically as new sensors are added to the system.





  




 💡 How it Works? 





  






  
The system has 2 sensors: DHT22 for monitoring temperature and humidity and the Photoresistor (LDR) sensor for measuring luminosity;

   
The buzzer will sound whenever the system enters an alarm situation;

  
Alarm situations:




  

  


    
Temperature < 10º or Temperature > 20º

    
Humidity > 60%

    
Luminosity < 500

  




  

  
If the system enters any alarm situation, the blue button next to the buzzer can be activated so the buzzer stops sounding;

  
The button can also be pressed at any time to disable the alarm system if the user does not wish to be notified.
