Sensors and meters in integrated HVAC-irrigation systems measure various parameters that are critical to the system’s performance and efficiency. These parameters include temperature, humidity, pressure, flow rate, and water quality. Temperature sensors measure the temperature of air, water, or soil, while humidity sensors monitor the level of moisture in the air. Pressure sensors measure the pressure of gases or liquids within the system, and flow meters track the flow rate of water or air through pipes or ducts. Water quality meters analyze the pH, dissolved oxygen, and other chemical properties of the water.
