ESP32 Project -Prototipe Hidroponik Sistem DFT Berbasis IoT-

Summary

This project presents the development of a hydroponic system using the Deep Flow Technique (DFT), designed for urban spaces where land is scarce. The system uses an SP32 microcontroller, various sensors (DHT11 for temperature and humidity, DS18B20 for water temperature), and actuators like fans and water pumps. It also incorporates UV lighting for plant photosynthesis, all of which can be monitored and controlled remotely via the Blink platform. The system provides real-time data on environmental conditions and automates plant care, offering a sustainable solution for modern agriculture with future improvements including power optimizations and sensor expansions.

Takeaways

• 😀 **Hydroponic System Prototype:** The project involves creating a hydroponic system using DFT (Deep Flow Technique), controlled by an ESP32 microcontroller.
• 😀 **Key Components:** The system uses ESP32, DHT11 sensor (temperature and humidity), DS18B20 sensor (water temperature), relays, water pump, fan, UV light, and an LCD display.
• 😀 **Wi-Fi Monitoring:** The system allows remote monitoring via a Blink app, sending real-time sensor data and system status to a server, accessible from a smartphone.
• 😀 **Temperature-Based Control:** When the air temperature exceeds 30°C, the system turns on the fan, and it turns off below this threshold.
• 😀 **UV Lighting Schedule:** The UV light and water pump operate between 6 AM and 5 PM to ensure proper lighting and water supply for the plants.
• 😀 **LCD Display:** The LCD screen shows real-time data, including air humidity, air temperature, and water temperature, updating every few seconds.
• 😀 **Software Structure:** The software integrates libraries for sensor reading, Wi-Fi connection, Blink communication, and relay control based on sensor data.
• 😀 **Relay Operation:** Relays control the pump and fan based on temperature readings, ensuring optimal conditions for the plants.
• 😀 **Power Supply Limitation:** The system struggles with power supply limitations, particularly for the fan and pump. An external power source like a battery or solar panel is recommended for improvement.
• 😀 **Future Enhancements:** Future upgrades include adding TDS and pH sensors for nutrient management, optimizing power supply, and possibly integrating solar panels for sustainability.

Q & A

What is the primary goal of the hydroponic prototype described in the script?

The primary goal of the hydroponic prototype is to create a system that allows plants to be grown efficiently using limited space, addressing the challenge of decreasing agricultural land due to increasing global population.

What components are used in the hydroponic system described in the script?

The components include an ESP32 microcontroller, DHT11 temperature and humidity sensor, DS18B20 water temperature sensor, a 4-channel relay module, mini fan, pump, UV light, LCD screen, and power supply.

How does the hydroponic system monitor and control temperature and humidity?

The system uses a DHT11 sensor to measure the air temperature and humidity, and the ESP32 processes the data. If the temperature exceeds a set threshold, the system activates a mini fan to cool the environment.

What role does the DS18B20 sensor play in the hydroponic system?

The DS18B20 sensor is used to measure the water temperature, which is crucial for maintaining the optimal conditions for plant growth in the hydroponic system.

How is the UV light used in the hydroponic system?

The UV light is used to simulate sunlight for plant photosynthesis, operating from 5 AM to 5 PM to ensure the plants receive adequate light during the day.

How does the system communicate with the user's smartphone?

The system sends data to a Blink server, which then forwards it to a mobile app, allowing the user to monitor temperature, humidity, and other conditions remotely.

What happens when the system is not connected to Wi-Fi?

When the system fails to connect to Wi-Fi, the LCD and serial monitor display a 'connecting' message, and the system continues to try to reconnect until successful.

What are the specific functions of the relay modules in the system?

The relay modules control the activation of the mini fan, pump, and UV light based on conditions such as temperature and time of day. They allow the system to manage the hydroponic environment effectively.

What improvements are suggested for the hydroponic system in the script?

The suggested improvements include adding external power sources like batteries or solar panels to stabilize the system's power, incorporating additional sensors (like TDS or pH sensors), and optimizing the UV light for better photosynthesis.

What challenges did the creator face with the power supply, and how did it affect the system's performance?

The creator faced issues with the power supply not being strong enough to run all components, especially the mini fan. This limited the system's ability to function at full capacity and required a more stable power source to improve performance.
