Regular maintenance and calibration of sensors and meters are critical to ensure the accuracy and reliability of the measurements in integrated HVAC-irrigation systems. Sensors and meters can drift over time, leading to inaccurate readings, which can affect the system’s performance and efficiency. Regular calibration ensures that the devices are measuring within their specified accuracy range. Additionally, regular maintenance helps to prevent faults, such as sensor fouling or corrosion, which can lead to system downtime or failure.
