P-line Web Sensor for measuring temperature, relative humidity and three binary inputs for two-states signals. Remote alarm.
The devices are equipped with two connectors for connection of the temperature and humidity external probes and three binary inputs for two-states signals. The dry contact or two-state voltage signal can be connect to the binary input.
Connect a smoke detector, a door contact and a water leak detector to the binary inputs for example.

| Probes - temperature and humidity | |
| Web Sensor is designed to measuring from digital temperature or humidity+temperature probes. Two channel device for maximum flexibility and efficiency of network resources usage (e.g. IP address). Maximum two cable probes can be connected. Temperature and temperature+humidity probes are available as optional accessories. Temperature can be displayed in degree of Celsius or degree of Fahrenheit. Relative humidity is measured at percent of RH. |
|
| Bináry inputs | |
| Web Sensor is equipped by three binary inputs. Binary inputs allow get values from dry contacts or binary sensors with voltage output. Type of the binary input is selectable in device setup. | |
| Ethernet interface | |
| 10Base-T/100Base-TX Ethernet interface via standard RJ45 connector. IP address can be obtain automatically from DHCP server or set manually. Internet protocol version 4 is supported only. | |
| WWW server | |
| Actual measured values are accessible via powerful embedded web server. Web pages are ready for access from mobile devices like smartphones and tablets. Device configuration via web pages is possible too. Web Sensor allows to user customize the design of web pages. | |
| History values memory | |
| Measured values are stored into history memory according selected time interval. Capacity of the memory is 1000 records for each channel. Values inside history memory are not backuped. Memory is cleared after device restart. | |
| History graphs | |
| Graphs with history values are accessible via web pages. Modern HTML5 canvas graphic component allows to use graphs from thousands of devices. It is not problem show graphs on tablets or smartphones. All modern web browsers are supported - Firefox, Opera, Chrome or Internet Explorer 9. | |
| History export to CSV | |
| History values can be exported for next processing by the CSV file. CSV file can be processed inside spreadsheet application like Microsoft Excel or OpenOffice Calc. Two formats of CSV file are supported - dot and comma decimal point separators. Timestamps inside CSV file are shown when device time is synchronised by the SNTP server. CSV file can be downloaded from web pages or periodically send as email attachment. | |
| Eventlog | |
| Alarm events from binary inputs, temperature and humidity channels are stored into eventlog. This log can be viewed on webpages or stored into CSV file. Capacity of this log file is 100 events. Values inside eventlog are not backuped. Log is cleared after device restart. | |
| Warning email are sent when measured value exceed selected limits. Emails are also send when values returns back into safe range. SMTP authentication is supported, but SSL not. Domain name for SMTP server address is supported. Emails with CSV file attachment can be sent at selected intervals. | |
| Modbus TCP protocol | |
| Modbus protocol for communication with SCADA systems or third party software. Device use Modbus TCP protocol version. Two Modbus clients can be connected to device at one moment | |
| Actual values via XML | |
| XML protocol for actual measured values reading. This protocol is suitable for Web Sensor integration into 3rd party SCADA systems. | |
| SNMP protocol | |
| SNMP version 1 protocol for IT infrastructure. Using SNMP protocol you can read actual measured values, alarm status and alarm parameters. Via SNMP protocol is also possible to get last 1000 measured values from history table. MIB tables with OID description are available. | |
| SNMP Trap | |
| SNMP Trap for IT infrastructure. Web Sensor allows sending Traps to selected Trap receiver server. Traps are sent in case of alarm on channel or at error states like unable to send email, unable to deliver SOAP message, etc. | |
| SOAP protocol | |
| Web Sensor allows to send currently measured values via SOAP v1.1 protocol. The device sends values in XML format to the web server. The advantage of this protocol is that communication is initialized by the device side. Due to it is not necessary use port forwarding. | |
| Syslog protocol | |
| Syslog protocol for IT infrastructure monitoring systems. The device allows sending text message to selected Syslog server. Messages are sent in case of alarm on channel or at error states like unable to send email, unable to deliver SOAP message, etc. | |
| SNTP protocol - time synchronization | |
| Time synchronisation with SNTP server. Actual time is shown at web pages and is necessary for timestamps inside CSV files. Synchronisation interval can be set to one day or to one hour. | |
| MIN/MAX memory | |
| Memory for minimum and maximum values. Memory is independent on values in history memory. Minimum and maximum values can be cleared according user requirements. | |
