Product information

Description

The TFA-Dostmann 30.5054.02 Indoor Temperature & Humidity Sensor is a compact freestanding device for monitoring room climate. It displays current temperature and relative humidity on a high-contrast e-ink display that is easy on the eyes and readable without glare. The display can show black text on white or an inverted white-on-black view. The device records and shows minimum and maximum values and also includes a clock with date or weekday indication. Its slim housing and multiple mounting options — fold-out stand, adhesive wall mount, nail hanging or rear magnet for metal surfaces — make it easy to place anywhere in the home.

Advantages

The e-ink display provides paper-like contrast and low power consumption, ensuring long battery life for the 3V battery operation. A smiley indicator signals when temperature and humidity are within the comfort zone, enabling quick assessment at a glance. Stored min/max readings can be viewed with a button press, and the integrated clock offers date or weekday display. Multiple mounting options offer flexible placement on shelves, walls or metal surfaces.
