Data Centre Environmental Sensor DCES-DTRHF-SER1CH-v1
Project description
Data centre environmental sensor - Dust, Temperature, Relative Humidity, Fan - Serial 1 channel - version 1.
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.
The device is close to maintenance free and can be integrated in compact
enclosures (for example tape drive tray or even an ATX PSU case...).
