Piezoelectric Airflow Sensor Reference Design

TIDA-00250

Design files

Overview

This Piezoelectric Airflow Sensor is intended for use in systems that require fan airflow detection. This can include server intake/exhaust airflow detection, as well as desktop computer airflow.  The Piezoelectric Airflow Sensor reference design is a simple, low cost solution which would help designers who are looking for a means to detect the presence or absence of fan airflow in existing systems.

Features

• Piezoelectric film sensor can be used in conjunction with an MSP430 microcontroller to provide a low-cost solution to detecting the presence or absence of fan airflow
• Small solution size with efficient layout considerations
• MSP430 LaunchPad BoosterPack form factor
• Easy to read GUI for interpreting airflow sensor results
• Circuit design has been tested and includes firmware, GUI, quick start quide
