WLAN Thermometer 1x Pt100

  • WLAN IoT thermometer for DIN rail mount

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.

Properties

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:
  • 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
