Temperature & humidity measurement via Single Pair Ethernet
From sensor to the cloud

The Thermo-Hygrometer SPE is a measuring device that records temperatures and humidity and makes the values available via Single Pair Ethernet. The device can be connected to the W&T Cloud, send MQTT messages and send push notifications to smartphones.

Properties

Sensor:

  • Temperature sensor:
    • Measuring range: -40°C...85°C
  • Relative humidity sensor:
    • Measuring range 0..100% RH, permissible ambient: 0..95% (non-condensing)

Connectivity:

  • Intuitive Web interface for simpler configuration
  • Monitor temperatures, humidity and curves via 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 temperature and humidity in the server room, network cabinet or office
    • Notifications when measured values exceed or fall below the limit
    • 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
