TME - Ethernet Thermometer Alarm Unit

TME is a simple temperature sensor with Ethernet interface. It measures temperatures ranging from -55°C to +125°C. Measured values can be read in several ways including TCP, UDP, HTTP (WEB), e-mail, SOAP, Modbus TCP and SNMP protocols. Thanks to this it is possible to choose a method suitable for particular application.

The temperature is sent in a simple ASCII format directly in degrees Celsius; there is no need of any additional conversion. It also enables communication with SNMP protocol (UDP) or sending an e-mail in case any of the pre-set limits is exceeded.

You can easily embed the temperature from TME to your WEB site using http GET. Measured temperature is also available in XML file or it can be sent as an http POST in XML format for further processing in a WEB service. (All temperature acquisition methods are on page 6.)

TME is configurable via WEB interface. TME is powered from an external PSU 5V (TME) or directly from ethernet network according to IEEE802.3af standard (TME PoE)
