the sensors come with a magnetic and double sided adhesives to easily mount them on any support.
About the Wireless Sensors.
The industry standard set by ASHRAE is to monitor each rack's environment with 6 temperature and 1 humidity sensor. Data Center operators face 2 key issues when monitoring temperature at a rack level using the ASHRAE standards: cabling and IP addresses. Traditional wired sensors are not an option: they require cabling and IP addresses. Wireless technology enables to overcome those issues: no cabling required and one IP address for many sensors.
This sensors can monitor 2 metrics: temperature and humidity. For humidity, 1 temperature and humidity sensor per rack is required when following the ASHRAE standard. Humidity should be kept within a 40-60% rH is critical to safeguard the hardware in the racks. ASHRAE recommends 6 temperature sensors per rack: 3 in the front of the rack and 3 at the back of the rack. The front of the rack monitors the intake temperature, the back of the rack the outtake temperature. The delta between intake and outtake temperature should never exceed 20C/35F. For temperature only, the wireless temperature
sensors can be used.
The sensors communicate over AES encrypted Zigbee protocol (2.4 Ghz) with the wireless hub that connects to the base unit. A wireless hub can accomodate up to 15 temperature+humidity sensors or up to 30 temperature only
sensors. The sensors have to be in a 10m/30ft line a sight range of the wireless hub
For easy installation in a rack, the sensors have a magnet at the back allowing them to snap into the rack. The sensors are powered using a coin battery (not included) and have a 1 year battery life span.
