Web Sensor T7511 - remote thermometer hygrometer barometer with Ethernet interface

code: T7511
Ambient temperature, relative humidity, atmospheric pressure t-line Web sensor. Remote alarm.

Web Sensor with relative humidity and temperature probe on the cable. Built-in atmospheric pressure sensor.

High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Dual line LCD is an advantage. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.

The device is supplied with T+RH probe with 1m cable. Cable lengths 2m or 4m available optionally.

WiFi Router Easy wireless communication using Web Sensor and optional  Wireless TP-LINK router.

  Online Ethernet Monitoring system

FEATURES:

Temperature, humidity an pressure
Temperature Humidity Web Sensor is designed for measuring from temperature and humidity cable probe and from built-in pressure sensor. High precision capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Web Sensor is designed for use in non-aggressive environment. Degrees Celsius and Fahrenheit are user selectable. Atmospheric pressure units are also user selectable.
Dew point and computed quantities
Ethernet Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy. User can select one of these interpretation.
Dual line LCD
Ethernet Large dual line LCD for simultaneous display of temperature, relative humidity or other calculated humidity interpretation is an advantage. Displayed values are user selectable. Display can be switched off.
Ethernet interface
Ethernet 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
WWW WWW config 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. The device allows you to user customize the design of web pages.
History values memory
1000 values 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
Graph 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.
Email
Email 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.
History export to CSV
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.
ModbusTCP protocol
Modbus 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 XML protocol for actual measured values reading. This protocol is suitable for device integration into 3rd party SCADA systems.
SNMP protocol
SNMP 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
Trap SNMP Trap for IT infrastructure. The device 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
SOAP The device 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 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
SNTP 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
MIN/MAX Memory for minimum and maximum values. Memory is independent on values in history memory. Minimum and maximum values can be cleared according user requirements.
