The black Explore Scientific Radio-Controlled Projection Clock with External Weather Sensor displays not just the time and day, but also the climate of the clock's environment and the current weather conditions with the help of the included wireless sensor that can be placed up to 98 feet away. The clock supports up to two additional wireless sensors (available separately) to provide a complete picture of the conditions indoors or outdoors. Rotating up to 180°, the projector arm ensures the clock can be placed in a wide variety of positions for your convenience. The clock can also be set manually or via radio signal to ensure accuracy.
