Environment, building equipment, industrial sites and ITsystems, as well as utilities, need to monitor their environment and operational conditions reliably and efficiently. An overview of selected variables such as temperature, pressure, dew point, lighting level, air quality, machine operation or vibration, provide a comprehensive picture of the state of the equipment and enable the operator to respond appropriately.

-
Icons and colors in SensDesk
In SensDesk, each sensor and device state has its specific color and icon. This scheme is consistent throughout the portal.
-
IP Access Filtering in Poseidon2 and Damocles2 units
Ip access filter allows you to define a range of trusted IP addresses that are allowed to access the Poseidon2 and Damocles2 units over HTTP and SNMP. Each protocol has its own range.
-
Link all your devices to your software – SensDesk concentrates values from multiple devices
HW group produces various devices with different characteristics and intended applications. Most devices are designed to be integrated into larger monitoring systems using SNMP, XML, Modbus/TCP or MQTT.
-
Modbus/TCP in Poseidon2 and Damocles2 family
The Modbus protocol itself allows to share the memory area for variables, e.g. the readings, over one of the physical interfaces. Modbus/TCP is an extension of this protocol for communication over Ethernet.
-
MQTT in practice on Poseidon2/Damocles2
MQTT is a lightweight TCP/IP protocol designed for use in IoT applications or in situations where many external devices send data to a central hub. The central hub can aggregate data and further distribute them to all subscribed devices.
-
My Graph function in the SensDesk portal – Compare your readings
The SensDesk cloud portal allows users to compare values from different sensors, even if different quantities and scales are involved. This function is called My Graph.
-
netGSM - How does it work with HW group devices
The netGSMfunction is designed for sharing one GSM modem connected to one unit with other devices on the same network. This means that more Poseidon units can send Alarm SMS using one GSM modem thus reducing network topology and costs.
-
New Actions module in the SensDesk portal
The SensDesk portal can send alarm messages and perform operations such as switching outputs based on readings retrieved from HW group devices. The new Actions module allows to manage the corresponding settings from one place.
-
Poseidon – hysteresis - Preventing false alarms
Poseidon monitoring unit sends SMS, e-mail, and SNMP traps whenever a sensor value is outside of a safe range. However, when the temperature or humidity fluctuates, the unit can send tens or hundreds of messages that are unnecessary and bother the user. A
