Poseidon2 3266

Poseidon2 3266 is a basic device for remote reading (monitoring) of sensors over the network. It measures temperature, voltage, and states of dry contacts (digital inputs) and other external sensors. It sends e-mail alerts to values out of a specified range, or connects to an environment monitoring system. Supports M2M protocols – SNMP (SNMPv3), Modbus/TCP, XML, and the Sensdesk.com online portal

Additional Product Information

Poseidon2 3266 monitors temperature and other sensors over a network in order to create a remote environment monitoring solution. Up to 8 sensors and 4 digital inputs (dry contacts) can be connected. Poseidon2 is connected to the LAN, reads measurements, and stores the measurements in its internal memory (data logger). The device is accessible via WEB and can send e-mails (or text messages).


We supply humidity and temperature sensors in indoor or outdoor designs, light intensity sensors, DC or AC current and voltage converters. Other sensors include smoke detectors, power failure detectors, water flood detection, and more.

Email & SMS Alerts

When a value is out of a specified range, Poseidon2 sends an e-mail, a SNMP Trap, or a text message (SMS). No software is necessary to send text messages over the GSM network. All HW group devices can send text messages (SMS) through a single central gateway, the HWg-SMS-GW. Just a single SIM card can serve all your devices.

Poseidon2 3266 can be connected to various third-party applications or cloud services using various protocols (SNMP, Modbus/TCP, XML, HWg-Push).
