Compact Websensor with built-in LCD screen to show temperature and humidity measurement. (Built-in sensors)

Use as a single temperature monitoring point or connect upto 100 units for a large multi-point/room monitoring solution using the powerful DBS Sensor Monitor Software

Sensormetrix are pleased to be able to offer the T3510 Ethernet temperature & humidity monitor solution. This device is perfect for a wide range of solutions, with a built-in temperature and humidity sensors. The T3510 can also can send an email or SMNP alert so you'll be notified if the device goes outside the safe limits set by you. At this price it's not worth risking expensive equipment from temperature related damage.

T3510 is wall mountable and requires just a Ethernet and power connection. Comes with free software for simple monitoring and datalogging or optional software if you have many T3510 monitoring back to one central sever.

Modes of Communication

Modbus TCP: Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe.
Telnet: -Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for measured values and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 100 sets of temperature, humidity, pressure + computed values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled.
WWW pages: User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature, humidity, pressure + computed values history.
SNMP: It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses).
SOAP: Online transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s.

Online transmitter enables to monitor measured values. In case of exceeding of adjusted limits warning message can be sent to specified addresses. There are the following options of alarm indication:

Alarm Indication Options

E-mail: In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message. Basic SMTP authentication is supported.
SNMP: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses).
WWW pages: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits active alarm is displayed on www page.
syslog: Online transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, after firmware change, after alarm termination, after communication error with SOAP server.

Synchronizing of time and record to www table and measured values history is enabled by SNTP via Internet

Dimensions of the case (W x H x D): 88 x 73 x 39.5 mm
