VIVOSUN THERMOMETER-HYGROMETER VPD BT THB1S Bluetooth weather station

Vivosun Bluetooth thermometer-hygrometer – precise measurement of temperature, humidity, and VPD

The Vivosun Bluetooth thermometer-hygrometer is an advanced device designed for accurate monitoring of environmental conditions in many places: from bedrooms and children's rooms, through basements, to greenhouses and grow tents. Thanks to its connection to a mobile app and fast real-time readings, it facilitates climate control in both home and plant cultivation applications.

Inside, it uses a Swiss-made smart sensor that provides very stable and reliable results. The device offers high precision temperature measurement with an accuracy of ±0.5°C and humidity measurement with an accuracy of ±5%RH. The set also includes an external sensor probe, which allows you to monitor conditions in a second location in parallel — this is particularly useful when you want to control, for example, the interior of a grow box and the space next to it, or different zones in a room.

A big advantage is its easy-to-use interface and convenient data display. The thermometer-hygrometer is equipped with a large LCD screen that displays current values and additional information to help you assess the environment. The built-in VPD (vapor pressure deficit) visualization function makes it easy to assess whether the climate is suitable for growth and flowering, for example. The device also records maximum and minimum temperature and humidity values, allowing you to quickly notice parameter spikes during the day or night. In addition, 3 comfort zones are used to easily show whether conditions are within the appropriate range.

Another important feature is remote data viewing and smart notifications. After pairing via Bluetooth with the Vivosun app, you can monitor temperature, humidity, and VPD in real time without having to approach the device. The app can send instant alerts when values exceed set thresholds, allowing you to respond quickly and maintain stable conditions in the room.

The device also offers a practical measurement archiving option: it provides 2 years of free data storage, allowing you to analyze the history of readings and better tailor conditions to your needs. Importantly, data can be exported at any time, e.g., for your own analysis or comparison of results.

This model is also ready for expansion with the Vivosun system. It can be used as an additional sensor and integrated with GrowHub E42 / E42A / E25 controllers, where GrowHub can act as a WiFi gateway. It can be paired with GrowHub E25 to add a display and temperature and humidity sensor, as well as connected to other Vivosun SGS devices such as AeroZesh or AeroLight, providing convenient visualization of temperature, humidity, and VPD data in a single ecosystem.
