TFA Digital alarm clock

With this handy alarm clock, you can always keep an eye on the current time and wake up on time. At the same time, thanks to integrated sensors for temperature and humidity, you can monitor the climate in your bedroom: For restful sleep, the temperature should be between 16 and 18 °C. Studies show that most people feel most comfortable in rooms with 40 to 60% humidity. By heating and ventilating strategically, you can not only create a pleasant climate and save on heating costs, but also detect the risk of mold due to excessive humidity early on. With its compact size of 68 x 24 x 40 mm, this alarm clock will fit perfectly on any bedside table and, weighing just 36 grams, is also a great companion while traveling. The clock is powered by a 3V CR2032 button cell (included).
