Monitoring and controlling temperature, humidity, air pressure, CO2 levels, light intensity, soil moisture, pH, and soil compaction in an environment using various sensors and equipment such as heaters, sun exposure, dehumidifiers, misters, shading, air conditioning, and fertilizers.

Temperature and humidity: detected using temperature and humidity sensors.
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 levels: detected using a carbon dioxide sensor.
Light intensity: detected using a photoelectric sensor.
1. 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.
1. Deep plowing, using earthworms and other organisms to alter soil compaction.
2. Use acidic or alkaline fertilizers to change pH values.
