Summary

In this video, the presenter demonstrates a Smart Garden project, which includes an automatic plant watering system and temperature control. Using the ESP8266 microcontroller, a soil moisture sensor, and a DHT11 temperature sensor, the system allows for remote control of water pumps and fans via the Blink platform. The project also includes manual and automatic modes for controlling the pump and fan based on soil moisture and temperature readings. The presenter explains how the system operates through both web and mobile app interfaces, offering a hands-on demonstration of the automation process.

Takeaways

• 😀 The video introduces a Smart Garden project that features an automatic plant watering system and temperature control.
• 😀 The project utilizes the Internet of Things (IoT) concept, allowing control of a water pump and fan through the Blink platform.
• 😀 The main components used in the project include an ESP8266 microcontroller, a two-channel relay module, and sensors like the soil moisture sensor and DHT11 for temperature measurement.
• 😀 The soil moisture sensor measures soil humidity, while the DHT11 sensor tracks ambient temperature, which is displayed on a web dashboard or mobile app.
• 😀 The water pump activates when the soil moisture is below 40% and deactivates when it exceeds 75%.
• 😀 The fan is controlled based on the temperature: it turns on when the temperature exceeds 31°C and turns off below 28°C.
• 😀 The system can operate in both manual and automatic modes, with manual mode allowing direct control of the water pump and fan.
• 😀 In auto mode, the water pump activates automatically when the soil moisture drops below 40%, and the fan works based on the preset temperature thresholds.
• 😀 The script demonstrates testing of the soil moisture sensor and the control of the water pump and fan through the Blink app.
• 😀 The video highlights the ability to monitor soil humidity and temperature in real-time through a user-friendly interface, making it practical for plant care.
• 😀 The Smart Garden project kit is available for purchase on Tokopedia and Shopee, with a guide and source code included.

Q & A

What is the purpose of the Smart Garden project demonstrated in the video?

The Smart Garden project aims to automate plant watering and control the temperature in a garden using IoT (Internet of Things) technology. It includes features like soil moisture monitoring and temperature control via a mobile app or web dashboard.

What are the key components used in the Smart Garden project?

The project uses an ESP8266 microcontroller, a 2-channel relay module, a soil moisture sensor (version 2.0), a DHT11 or DHT22 temperature and humidity sensor, a 5V mini water pump, and a fan for cooling control.

How does the soil moisture sensor function in the project?

The soil moisture sensor measures the moisture level of the soil. When the moisture level is below 40%, the water pump is activated to water the plants, and when it exceeds 75%, the pump is turned off automatically.

What happens when the temperature exceeds 31°C in the Smart Garden system?

When the temperature exceeds 31°C, the fan or exhaust system is automatically activated to cool the area. If the temperature drops below 28°C, the fan will be turned off.

Can the system be controlled manually, and if so, how?

Yes, the system can be controlled manually through the mobile app or web dashboard. There are options to manually turn on/off the water pump and the fan, as well as switch between automatic and manual modes.

How does the system operate in auto mode?

In auto mode, the system automatically controls the water pump based on the soil moisture level and the fan based on the temperature. The water pump is activated when the soil moisture drops below 40% and deactivates when it reaches 75%. The fan activates when the temperature exceeds 31°C and turns off below 28°C.

What happens if the system is set to manual mode?

In manual mode, the water pump and fan can be individually controlled by the user via the app or web dashboard. The automatic functions based on temperature and moisture are disabled in this mode.

What is the role of the DHT11 sensor in the project?

The DHT11 sensor measures the temperature and humidity in the air. The data is used to control the fan's operation—activating it when the temperature exceeds a certain threshold (31°C) and turning it off when it drops below 28°C.

How did the presenter test the soil moisture sensor and the fan's behavior?

The presenter demonstrated the soil moisture sensor's function by adjusting the moisture level of the soil and watching the water pump turn on/off accordingly. They also tested the fan by increasing and decreasing the temperature using a blower to see how the fan responded to temperature changes.

Where can viewers purchase the Smart Garden kit, and what does it include?

The Smart Garden kit can be purchased from DT Production's store on Tokopedia or Shopee. It includes a project kit, a guide, and the source code for building the system.
