Poseidon2 3266 Environment Monitors can support up to eight sensors connected over a 1-Wire UNI or 1-Wire sensor and up to 4 detectors connected to digital inputs. The device can be monitored remotely over the internet using the HWg Cloud or SensDesk portals in combination and the SensDesk Mobile app (iOS and Android). The Poseidon2 also works with HWg-PDMS and HWg-Trigger software packages and has a built-in web server for ease of configuration.

Poseidon2 devices are designed to monitor and control sensors and digital Input/Output (I/O) signals over a network using secure M2M protocols (HTTPs, IPv6, SNMPv3). The devices can be integrated into a wide range of monitoring and control systems and support over fifty SNMP and SCADA applications. The MQTT protocol is built-in to allow integration to IoT applications.

Poseidon2 TSet and THSet Kits

With the TSet, the Poseidon2 3266 is supplied with a 3m temperature sensor, power adaptor and pair of door contacts. In the THSet the sensor is a 3m temperature & humidity sensor.

Key Features

  • Eight 1-Wire UNI/1-Wire Inputs
  • Four Digital Input with 32-bit S0 pulse counters (retain values even if the power fails)
  • Data Logger for more than 250,000 records
  • Five SNMP Traps, five email and five SMS and Phone Call Rings via external GSM gateway or modem
  • MQTT compatibility to allow connection to IoT Hubs, Microsoft Azure, AWS IoT, Bluemix Internet of Things and other cloud services
  • Connected via LAN and configured via built-in web server
  • A DI state change sends an alert by email, SMS+Ring, SNMP Trap or activates a remote relay on another Damocles2 or Poseidon2 device
  • S0 pulses can be converted to cost per time period and exported to MS Excel using HWg-PDMS software
  • Compatible with a range of third-party software (including SCADA). Examples include Borland C++, MS Visual, VB, C#, PHP, JAVA and more

Poseidon2 Internet of Things (IoT) Solutions

The Poseidon2 is an IoT device monitoring solution and provides:

  • Supports data transfer via Ethernet
  • Provides quick view real-time data on the HWg Cloud and SensDesk Cloud portals
  • Sends data via email, custom software and Cloud third-party applications
  • Uses standard protocols including HTTPs, IPv6, SNMPv3 and MQTT

Poseidon2 devices have an Ethernet interface and can transfer current values and buffer stored data. The data can be transmitted to the HWg Cloud or SensDesk portals using HWg-Push software or passed via HWg-PDMS software to third-party software using MQTT IO protocols and run on Microsoft Azure or Amazon AWS servers. Data can also be emailed to PDMS and downloaded from a POP3 or secured POP3S mailbox.
