Case Study 33: S0 pulse counter with SNMP and Modbus/TCP output

Case study on connecting electricity, gas or water meters to the Ethernet and reading values over the SNMP or Modbus/TCP protocols. Pulse outputs from 3rd party meters (S0 interface) are connected to the Damocles Ethernet I/O unit. Each Digital Input on the Damocles unit features a 32-bit pulse counter. The value of this counter can be read out over the web using most M2M protocols (SNMP, XML, Modbus/TCP).

New product: illumination sensor

Light 1Wire-UNI is new illumination sensor. Simple light intensity sensor for indoor use. The sensor is designed for use with Ares, Poseidon, and other HW group products. Connects to the 1-Wire UNI bus (RJ11).is new illumination sensor. Simple light intensity sensor for indoor use. The sensor is designed for use with Ares, Poseidon, and other HW group products.

Case Study: GSM temperature monitoring and logging, e-mail alerts over GPRS

Portable solution for remote temperature monitoring and logging, suitable for monitoring rooms or equipment. Excessive temperature sensed by a probe is signaled by a SMS or a ring. GSM thermometer Ares12 continuously logs the temperature in its internal memory and periodically e-mails the log over GPRS. The logs can be imported to MS Excel.

HWg-Push Nagios collector

Nagios application for collecting data from IP sensors that support the HWg-Push protocol. Thanks to the application, the Nagios SNMP monitoring system can include sensors in GSM networks or behind firewalls.

HWg-Juno: News

New presentation for HWg-Juno and model specifications. Simply connect your Omnicast IP based camera system by Genetec with external sensors.

How to connect HWg-Ares with PDMS

Web presentation on how to connect data from a GSM/GPRS unit HWg-Ares with windows application PDMS. GSM unit can be placed anywhere under GSM signal coverage. It can be placed even in a vehicle.. You will have the sensor data in your notebook every hour.

Spider

Spider connects 4 dry contacts or 1-Wire bus RJ11 sensors to Poseidon 2250 and RS-485 (RJ45) bus. Spider is an active converter between RS-485 and 1-Wire bus. Spider units can be daisy chain connected.

Spider makes it easier to connect more sensors over longer distances using the RS-485 bus. Suitable for applications in rooms and larger areas.

Typical application

• Enlarging the number of inputs for connection of dry contacts for Poseidon 2250.
• Gathering values from 19” racks, RS-485 bus runs along the wall.
• Temperature monitoring in supermarket freezers, RS-485 bus runs along the wall behind the freezers.
