Automated Garden Watering using Soil Moisture Sensors and MQTT
11.12.2024 - Engine: Gemini
Project: Automated Garden Irrigation with Soil Moisture Sensors and MQTT Control
Objectives
- Automate garden irrigation based on soil moisture measurements
- Monitor and control the system via MQTT protocol
Components
- Microcontroller (e.g., Raspberry Pi, Arduino)
- Soil moisture sensor
- Water pump
- MQTT broker
- MQTT client
Procedure
1. Hardware Setup:
- Connect the soil moisture sensor to the microcontroller.
- Connect the water pump to the microcontroller according to manufacturer's instructions.
2. Software Setup:
- Install MQTT broker and client on the microcontroller.
- Program the logic to process soil moisture measurements and control irrigation.
- Publish soil moisture data over MQTT.
- Subscribe to MQTT topics for commands and notifications.
3. MQTT Configuration:
- Create an MQTT topic for soil moisture data.
- Create an MQTT topic for irrigation commands.
- Create an MQTT topic for notifications.
4. User Interface:
- Create a web interface or mobile application to monitor soil moisture data and trigger irrigation.
- Connect the user interface to the MQTT broker.
5. Workflow:
- Soil moisture sensor measures soil moisture and publishes data over MQTT.
- If soil moisture falls below a threshold, the MQTT client triggers irrigation.
- The water pump turns on and irrigates the garden.
- The system sends notifications over MQTT when the irrigation cycle is complete.
Benefits
- Optimized garden irrigation based on real-time moisture measurements
- Reduced water consumption
- Remote control and monitoring
- Irrigation status notifications
