OW-SERVER-WIFI 138.00 €
1-Wire to WiFi Server (Rev. 2)
The OW-SERVER-WIFI is an inexpensive WiFi to 1-Wire interface that is designed to efficiently monitor and control 1-Wire devices. The OW-SERVER-WIFI will allow you to use industry standard WiFi products (switches, hubs, etc.) to build the backbone of your 1-Wire based sensor/control system. This provides several important benefits: First, 1-Wire networks can be easily distributed over great distances without having to deal with the challenges associated with the installation of physically large 1-Wire networks. By distributing the 1-Wire networks, the individual 1-Wire MicroLans can be kept to a smaller physical size, thereby improving responsiveness/reliability and decreasing installation costs. Second, since the OW-SERVER-WIFI communicates over standard WiFi, you can take advantage of existing corporate WLAN, the Internet, and in-house MIS expertise for building out and maintaining the backbone of your sensor network.

The OW-SERVER-WIFI has been designed in such a way to minimize the amount of network resources needed to monitor 1-Wire devices. It maintains the latest readings of its 1-Wire devices which are updated every 2 seconds. This enables the OW-SERVER-WIFI to deliver a current reading without waiting for a time intensive temperature conversion (or other conversion) to be performed. Also, the OW-SERVER-WIFI is designed to push data when a user defined alarm occurs via SNMP traps. This significantly reduces the necessary polling rate for many applications while still supplying assurance that any problem will be detected in a timely manner.

A number of Ethernet protocols are used by the OW-Server including HTTP and SNMP. The HTTP interface provides a simple means to configure the OW-SERVER, 1-Wire sensors and collect real-time sensor data. The real-time data is presented in a number of ways including:

  • Overview Page - containing primary attributes (e.g. ROM Id, Device Type, Temperature Readings) of each sensor, a graph of all the sensors with the user selected value (e.g. Temperature, Humidity, Light Level, Latch State) and a "Download" button for exporting the graph's data in a CSV format.
  • Sensor Pages - includes all of the sensor's data, a graph of up to three user selected sensor values and a "Download" button for exporting the graph's data in a CSV format.
  • Advanced Details Page - contains all of the data from the connected sensors. AJAX techniques automatically updates the information insuring the data being displayed is current.

The SNMP interface is divided into 3 sections: edsEnterprise, owTrap and owDevices. The edsEnterprise section presents basic product information, such as name and version. The owTrap section is where you define the IP address the trap should be sent, the high alarm, low alarm, and the hysteresis. The owDevices section data similar to the Overview and Devices webpage.

Applications
  • Server Room Monitoring
  • SCADA Systems
  • HVAC

Examples of Supported Devices

Caution
A special cable may be required when using the OW-SERVER-WIFI with pluggable 1-wire devices from other manufacturers, e.g. the MultiSensor family from iButtonLink. Failure to comply will result in damage to the connected 1-wire device. Please check the pinout of each device before connecting it to the OW-SERVER-WIFI.
