Description

he TIDA-01070 TI design provides a reference for monitoring airflow efficiency and temperature through HVAC systems. The 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.
