## Summary description

ATEN Temperature & Humidity Sensor EA1240 is an environmental monitoring sensor designed to measure ambient temperature and relative humidity. The unit weighs 80 g and comes in compact retail packaging (110 × 160 mm). It provides real-time environmental data for server rooms, network closets, labs or other installations where temperature and humidity tracking is required.

## Long description

ATEN Temperature & Humidity Sensor is an optional environmental probe designed to work with ATEN Power Distribution Units (PDUs) to measure temperature and relative humidity. The sensor provides real-time environmental readings and supports alarm notifications when measured values exceed user-defined minimum or maximum thresholds. It can be added to PDU installations to extend monitoring capabilities for data center and equipment-room environments.
Advantages
The sensor enables centralized environmental monitoring together with ATEN PDUs, offering configurable temperature and humidity thresholds and alarm alerts. Installation is optional, allowing PDUs to operate without sensors, while providing the option to add environmental monitoring when comprehensive energy and environment management is required.
Suitable for
Data centers and server rooms
Network cabinets and communication closets
Telecom sites and equipment racks
Any facility requiring temperature and humidity monitoring alongside power distribution
Key specifications
Measures temperature and relative humidity
Provides real-time environmental readings and alarm support for configurable thresholds
Compact, lightweight probe (product weight ~80 g; packaged dimensions: width 110 mm, depth 160 mm)
How to use
Connect the sensor probe to a compatible ATEN PDU according to the PDU installation instructions. Configure threshold values for temperature and humidity through the PDU management interface to enable alarms and logging. Place the probe in the location within the rack or room that best represents the environment you want to monitor, avoiding direct airflow from vents for accurate readings.
Usage recommendations
Use the sensor as part of an ATEN PDU installation to achieve integrated environmental and power monitoring. Position the probe at rack inlet height for representative measurements and periodically verify calibration and connections to ensure reliable alarms and data.
