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.

The standard Thermo-Hygrometer comes with a 3-pin screw terminal for SPE connection. As variant #57723 TB901191 (see Accessories), the device is also available with M8 screw connector (IEC63171-5).

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:
