With this handy alarm clock, you always have the current time in view and will be woken up on time. At the same time, thanks to integrated sensors for temperature and humidity, you can keep an eye on the climate in your bedroom: For a 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 nightstand and, weighing just 36 grams, is also a great travel companion. The clock is powered by a 3V CR2032 button cell (included).
