About

CERN DCES is an environmental sensor for Data Centers that continuously measures airborne particle density in high airflow as well as temperature and relative humidity.

It can control its fan speed if needed (PWM controlled fans) and monitors FAN rotational speed (tachometer equipped fans) for precise airflow control and monitoring.

It is close to maintenance free and can be integrated in compact enclosures (for example tape drive tray or even an ATX PSU case…).

You can find more information on CERN DCES project on its openhardware repository page.
