- Temperature and humidity: detected using temperature and humidity sensors.
- Use heating equipment, sunlight for heating, and natural ventilation, shading, or air conditioning for cooling.
- Reduce humidity with a dehumidifier, increase humidity with misting.
- Air pressure: detected using a pressure sensor.
- Carbon dioxide levels: detected using a carbon dioxide sensor.
- Light intensity: detected using a photoelectric sensor.
- Change lighting conditions, such as shading, adding films to alter brightness or color.
- Soil compaction and pH value: measured using a soil hardness meter, soil moisture sensor, and pH sensor.
- Deep plowing, using earthworms and other organisms to alter soil compaction.
- Use acidic or alkaline fertilizers to change pH values.
