The web thermo-hygrobarometer records temperature, humidity and air pressure via a combination sensor. It offers a wide range of protocols and enables easy integration into Node-RED environments as well as the free W&T Cloud.
In addition to a temperature sensor, the Web-Thermo-Hygrometer++ also has a drift-free sensor for humidity, for continuous use in high humidity.
Web-Thermometer Air Quality
The Air Quality web thermometer records temperature, humidity and air pressure via a combination sensor. It offers a wide range of protocols and enables easy integration into NodeRED environments and the free W&T Cloud.
The NTC web thermometer is equipped with a resistance sensor with a negative temperature coefficient and detects temperatures between -45°C and 75°C.
The Pt100/Pt1000 web thermometer records temperatures via any platinum resistance sensors from the Pt100/Pt1000 series. Models with one, two and eight measuring inputs are available. Compatible Pt100 or Pt1000 sensors for almost all applications are available from various manufacturers.
