Overview
A projector in the clock body throws the time onto a surface, while a wireless sensor reports outdoor temperature and humidity back to the display. The case is plastic and stands on a tabletop with alarm and snooze controls.
Projection means the time can be read from bed without turning toward a screen, and the weather readings add useful context for the morning. Battery power makes it easy to place anywhere, though every battery in the setup is something to replace.
Who it's for
A bedside table, kid's room or living room where the time is read from a pillow is the setting. Anyone wanting a mains powered clock or an outdoor sensor with documented range should check the listing details first.
Pros and cons
- Projects the time onto a surface

- Alarm with snooze
- Runs on batteries
- Outdoor sensor battery needs not listed
Performance notes
A projector lamp throws the digits, and the brightness setting decides whether the glow disturbs sleep. The wireless sensor sends temperature and humidity to the base, so reading accuracy and range depend on where the sensor is placed and how far it is from the base. Battery powered operation means the readings fade or stop as cells run down.
