The first idea:Intelligent Automatic Flower Watering Device
1. Project Background
1.1 Project Inspiration
In household or school settings, plant care often faces the following challenges:
- Unattended During Holidays or Trips: Plants suffer from lack of water, leading to wilting or even death.
- Irregular Manual Watering: Relying on manual operations can result in overwatering or prolonged drought, affecting plant health.
1.2 Solution
Design an IoT-based automatic flower watering device with the following features:
- On-Demand Precision Watering: Real-time soil moisture monitoring via sensors, triggering irrigation only when needed.
- Scheduled Watering Function: Support for preset watering cycles to accommodate different plant needs.
- Low Power Consumption and Cost-Effective: Suitable for homes, schools, offices, etc., ensuring long-term stable operation.
2. System Design and Principles
The system is based on IoT technology, using Arduino Uno as the main controller along with various sensors and actuators.
2.1 Project Sketch
2.2 Project Core Components
| Component Name (Chinese/English) | Function Description |
|---|---|
| Water Storage Tank(储水容器) | Stores irrigation water, capacity can be expanded |
| Water Pump(水泵) | Transfers water from the tank to the plant roots |
| Relay Module(继电器模块 ) | Controls the pump's on/off switch to ensure safe operation |
| Arduino Uno (控制板) | System core, processes sensor data and executes control logic |
| Soil Moisture Sensor(土壤湿度传感器) | Monitors real-time soil moisture levels, feedback to the control board |
3. Extended Application Scenarios
3.1 Cross-Domain Adaptation
- Aquaculture:
- Fish Tank Automatic Refill System: Monitors water levels and triggers refilling.
- Pet Care:
- Pet Drinking Fountain: Periodically replenishes clean water.
- Agricultural Irrigation:
- Small Greenhouse Humidity Control: Requires upgrading pump power and increasing the number of sensors.
