Introducing SNS™ Temperature and Humidity Sensors
SNS™ Temperature and Humidity Sensors provide monitoring and logging of environmental
conditions throughout your facilities. SNS Temperature and Humidity Sensors (sensor devices)
communicate with the Synchronized Network Solutions (SNS) Application Management Platform
(AMP)/Network Time Protocol (NTP) server over wireless 802.11 b/g networks. (Some sensor
devices can also communicate over the wired Ethernet network.) Figure 1 shows the architecture of
an SNS Temperature and Humidity Sensors network.
Sensor Devices and Accessories
Primex Wireless offers battery- and AC-powered sensor devices and probes. An important
accessory for both AC- and battery powered external probe sensors is the SNS thermobuffer, which
enables sensor readings to be based on the temperature of the refrigerated assets rather than on
the air temperature.
AC-powered Sensor Devices and Accessories
Table 1 and Table 2 describe the AC-powered sensor devices and accessories. For more on AC-
powered sensor devices, see Features of SNS AC-powered Sensor Devices on page 12.
