Measure, log and report...

The WLAN Thermometer is a device that measures temperatures and makes the values available in the network via WLAN. The device can be connected with the W&T cloud, send MQTT messages or push notifications to smart phones.

Sensor:

• Pt100 temperature sensor:
  • Measuring range of W&T probe: -50°C...180°C
  • Measuring input: -200°C...650°C

Connectivity:

• Operation in Access Point mode or WLAN Client mode possible.
• Intuitive Web interface for simpler configuration
• Monitor temperatures and trends with your browser
• Alarm and reporting function:
  • MQTT messages
  • Push notifications to a phone using ntfy.sh
  • Activation code for the W&T Cloud Access included in scope of delivery
• Single value query:
  • Direct access to current measurement values via HTTP or TCP sockets.
• Current Industry 4.0 protocols:
  • MQTT support
• Possible applications:
  • Monitor temperatures in the server room, network cabinet or office
  • Messages when high or low temperature limits are exceeded
  • Green IT: Monitor efficiency of the server room climate control

Data logger:

• local, volatile data memory for two data
• Document measurement data online in the W&T Cloud and access from anywhere in the world
