HVAC Coil Airflow Sensor Reference Design for Predictive Maintenance in Air Filter Replacement
Description
This design provides a reference for monitoring airflow efficiency and temperature through heat ventilation and air conditioner (HVAC) systems. The reference design is used in conjunction with solid state relays and piezoelectric vibration sensors to monitor and react accordingly to low airflow and low temperature conditions through the air handler. The system also includes a calibration algorithm for consistent performance across all system setups.
