Environmental temperature and humidity are monitored using temperature and humidity sensors. Heating equipment and sunlight are used to increase temperature, while natural ventilation, shading, or air conditioning systems are used to decrease temperature. Dehumidifiers are used to reduce humidity, while misting is used to increase humidity. Air pressure is monitored using a pressure sensor. Carbon dioxide levels are monitored using a carbon dioxide sensor. Light levels are monitored using a light sensor. Changes in light conditions, such as shading or adding film to alter brightness or color, can be made. Soil compaction and pH levels are monitored using a soil hardness meter, soil moisture sensor, and pH sensor. Soil compaction can be altered by deep plowing or using organisms like earthworms. pH levels can be changed using acidic or alkaline fertilizers.

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