180 High Definition Projection: The projection clock uses an adjustable 180 angle to project the time in crisp images on the wall or ceiling at a distance of 2-3 metres. The clear projection allows you to easily read the time and the soft light will not disturb your sleep. Temperature Display: It has an integrated thermometer that can be read in C or F and a hygrometer that provides real-time updates on humidity and temperature. The temperature range is between -9C and +50C (15.8 to 122 degrees Fahrenheit) and is extremely accurate. This allows you to check the current temperature and protect yourself from hypothermia. Double alarm clock with snooze: The digital clock can easily set two separate alarm times. You can set it to your favourite radio station or alarm tone. The dual alarm clock has a snooze function that allows you to pause the alarm for ten minutes and take a nap. An extremely user-friendly function. Multi-function alarm clock: The projection thermometer alarm clock displays the room temperature, humidity, time and date. Displaying temperature and humidity helps you ensure a comfortable indoor environment and remind your family to dress appropriately to avoid colds and the like. Double power supply via USB and battery: The double alarm clock projection clock can be powered by the supplied USB cable or with 2 AA batteries (not included). If you have connected the USB cable, you can use the USB charging port to charge external devices, which ensures that your device does not switch off and avoids tedious reconfigurations after a power failure. Please note: If the device is powered by batteries, charging external devices is not possible.
