Poseidon 3268: WEB thermometer & I/O with SNMP
Ethernet temperature / humidity monitoring with 2 relay outputs and 4 dry contact inputs (Web, SNMP, and E-mail). Output relays can be controlled over the Web.
| Poseidon model 3268 can notice operator of crisis situation in various method (switched on/switched off contact, temperature or humidity out of set range).
When a Alarm occurs, the device sends you Email and notice Your NMS (Network Management Software) over SNMP.
Configuration and current values over graphic WWW interface.
- 2 relay outputs to control external devices
- 4 inputs to connect contact
- You can connect up to 4 temperature or humidity sensors.
- Typical use:
- Switch contact to send email or SNMP Trap to several recipients.
- Turn on external cooling fan and notify an operator after temperature gets out of preset range

What Poseidon 3268 measures
Sensors are connected over 1-Wire (RJ12), total wiring length must not exceed 10 meters. Each sensor monitors whether the value is in set range (including inputs for connecting contacts). It warns about set range exceeding (Alarm status) via Email or sending SNMP trap.
Compatible probes
- Temperature - Temp-1Wire (detailed photo)
Temperature probes, different lengths of connecting cables according to ordering number:
600 005 = 3 meters long, 600 242 = 1 meters long, 600 056 = 10 meters long)
- Humidity - Humid-1Wire (detailed photo)
Humidity probe, long:
600 279 = 3 meters long, 600 278 = 1 meters long)
- 4 inputs for Dry Contact
>> Value sensors
Topology

- WEB (HTML)
Values and state of sensors are presented on WWW page. The page is automatically reloaded every 5 second. There is a link to Flash Setup from main HTML page, update FirmWare and others
- XML
All sensor's values as well as alarm status information are available in XML files (temper.xml) and any application can log it from XML tags - more information
- SNMP
SNMP is protocol for monitoring of telecommunication devices, network infrastructure and related technology. The Poseidon is fully controllable over SNMP (v1, partially v2) - more information
- Modbus/TCP
Modbus/TCP is industrial standard for input from sensors and output to visualizing and SCADA systems. All values are available over Modbus/TCP - more information
- Alarms
- SNMP Traps
In case of exceeding "Safe Range" the sensor gets to Alarm status. To notify of this a SNMP Trap including alarm status description is sent to configured IP address - more information
- Email
In case of exceeding "Safe Range" the sensor gets to Alarm status. To notify of this a Email including alarm status description is sent to configured email address - more information

Which software to use
- Configuration: UDP Config - IP address configuration
- Event processing: PD Trigger - reacts to events
- Monitoring and logging: HWg-PDMS - Monitoring software with MS Excel reporting
- Visualization: CapTemp - Process monitoring and control
- Other applications: Third-party SNMP software
- For programmers: HWg-SDK contains interface descriptions and examples of using M2M protocols in several programming languages
PD Trigger application example
With the PD Trigger application for Windows, it is possible to receive alarms (SNMP traps) from an unlimited number of Poseidon products and define conditions and actions based on the originating device and the probe name. For example:
- In case of air conditioning failure in server room A, send a SMS to Peter
- In case of alarm in server room B, send e-mail to Tom
- In case of electricity supply failure anywhere, send SMS to Peter and turn on a warning light at the receptionist's desk
