Poseidon 3266: SNMP Thermometer & DI
Temperature / humidity measurement and monitoring of 4 dry contacts over a LAN (Web, SNMP, E-mail). A MS Excel reporting software with is graphs included for free.
| The Poseidon 3266 is a SNMP and web enabled environmental monitor (temperature, humidity, dry contact).
Four digital inputs (dry contacts) can be used for connecting door contacts, smoke detectors, water flood detectors, detectors of cooling fan failure or 230V supply failure.
Poseidon alerts you by Email or SNMP Trap in case a value is out of a defined range. When an input contact is closed, Poseidon alerts you by email or a SNMP trap. The alert can be delayed by a defined time (an e-mail is sent if a cabinet door has been open for more than 5 minutes).
- You can connect up to 5 temperature or humidity sensors.
- 4 dry contact inputs (Door contacts, power or smoke detectors)
- Opened door or temperature over limit will send an Email or SNMP trap.

With the HWg-PD Trigger software, alerts can be redirected to SMS or processed according to the PD Trigger rules. You can switch remote relay over IP or shut down a PC.
In a typical application, Poseidon 3266 monitors the environment and controls the doors in cabinets or technology rooms (telecommunication nodes, rack rooms, server rooms).

Application
Sensors
1-Wire sensors
- Total bus length max 60 m
- Each sensor has its own SafeRange. When the range is exceeded (alarm), e-mail or SNMP trap is invoked.
DI (Dry contact inputs) for detectors:

Topology

- WEB (HTML)
Values and state of sensors are presented on WWW page. The page is automatically reloaded every 5 seconds. There is a link to the Flash Setup, FirmWare update and others from the main HTML page.
- XML
All sensor's values as well as alarm status information are available in XML files (values.xml) and any application can log it from XML tags - more information
- SNMP
SNMP is a protocol for monitoring 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 an 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
- Simple Visualization: SNMPcap - I/O and sensors
- 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 en 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
