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)

Economical Ethernet Temperature/Humidity email Alarm

The HWg-STE web thermometer is an Ethernet based two channel alarm unit configured using a built-in web server. The HWg-STE web thermometer is configured using a built-in web server which can also show the current temperature (and humidity). If the temperature (or humidity) exceeds a specified threshold, an e-mail alert is sent. The HWg-STE Thermometer is also fully SNMP compatible. Free windows software HWg-PDMS for datalogging, graphical overview and MS Excel export is included.

The HWg STE represents an effective and economic solutions in the applications like air-conditioning failure, heating system monitoring, cooler/freezer monitoring, heating optimization and food storage.

Ethernet based Environmental Monitor sends email Alarms

The Poseidon 3268 is a simple Ethernet based stand-alone device which can send an email alarm when up to 4 monitored temperature or humidity sensors exceeds their defined range. The Poseidon 3266 also has 4 contact-closure inputs which can be used to trigger alarms on state change and there are 2 relay outputs which can be used to reset servers, or switch on a fan, etc.

Temperature or combined temperature/humidity sensors can be connected via RJ11 cable using the 1-wire protocol. Sensors are simply connected in a serial chain using RJ11 cable. These can be up to 10m away from the Poseidon 3268. You can assign a name to each sensor and also define high and low alarm limits. When the parameter goes outside these limits, the Poseidon 3266 can send user defined email alarm messages and toggle the output relays.

Once the Poseidon 3268 is connected to the LAN, you can run the free UDP setup utility, which will search the LAN to find all attached devices. You can then specify your desired Network address parameters. Once this is done, you can simply access the I/O data from a web browser. There is also a flash-based version.

All sensor's values as well as alarm status information are available from XML files (temper.xml) and any application can log it from XML tags. The Poseidon 3268 also supports the Modbus/TCP protocol, so it is easy to integrate with common SCADA packages such as DAQFactory.

Typical applications include monitoring conditions in server rooms, switch-boards, cold-storage buildings, freezers and fridges and other environmental monitoring tasks.
