The CyberPower Environmental Sensor (SNEV001) provides for UPS monitoring and management. Its two RJ45 Ethernet Ports allows for a max of 8 units to be daisy chained. Its four input dry contact closures allow users to monitor up to four other connected devices such as door alarms, security switches, and security systems. For real-time temperature and humidity readings of a datacenter, IT closet, or other critical environment, combine the SNEV001 with a CyberPower Remote Management Card, sold separately. Administrators can define temperature parameters in Fahrenheit or Celsius, and rising temperatures will prompt the RMCARD to send a predefined notification. The SNEV001 comes with a three-year warranty.
