The Power-over-Ethernet (PoE) Low-Temperature Sensor uses a glass-coated platinum RTD transducer to accurately measure temperatures from -200°C to +162°C (-328°F to 325°F). The Low-Temperature Sensor outputs the ambient temperature in degrees Celsius or Fahrenheit and alert the user when a temperature threshold has been crossed.
The Power-over-Ethernet (PoE) Sensor products measure various conditions (environmental, power, access). All devices come with flexible settings — including notifications, alerts, reports, and maps — can be customized in the iMonnit online sensor management interface.
No PoE infrastructure in your building? Plug the PoE•X Sensors into your Ethernet network and then power the sensors with the optional AC power supply.
