SMARTRO SC91 Projection Alarm Clock with Weather Station — Red Rotary Projection, Dual Alarms & Indoor/Outdoor Sensors

The SMARTRO SC91 is a projection alarm clock and wireless weather station that displays time, indoor/outdoor temperature, humidity, and a red ceiling/wall projection for easy nighttime viewing.

The SC91 combines an easy-to-read 4.5" LCD weather display with a rotatable red projection, indoor/outdoor sensors, and dual alarms to help you monitor comfort and plan your day. It is powered by a DC adapter and supports one included wireless remote sensor (up to three total). The unit also shows pressure and temperature trends and gives mold-risk indicators to keep your living spaces comfortable.

How clear is the projected time and can I adjust its position?

The SC91 projects the time and temperature in a soft red glow that’s visible on walls or ceilings, ideal for checking the time at night without turning on a bright light. You can change the projection brightness and rotate the projector head 180 degrees so the image lines up correctly no matter where you place the clock.

• Adjustable projection angle for ceiling or wall placement
• Multiple brightness levels for comfortable night viewing
• Red projection color for low-glare visibility
• Projector head reversible by 180° for flexible positioning

What temperature and humidity information does the SC91 provide?

This unit shows both indoor and outdoor temperatures plus humidity readings from the included wireless sensor, helping you track conditions that affect comfort. The display cycles through readings and is accurate enough for everyday home use, with a humidity monitor and mold-risk alert for quick assessment.

• Indoor and outdoor temperature readouts
• Relative humidity for indoor comfort tracking
• Mold risk and mold alerts based on humidity levels
• Professional-grade sensor for reliable household monitoring

Can I expand the system and how is the wireless sensor range?

You can pair up to three wireless remote sensors with the SC91 to monitor multiple rooms or outdoor locations (only one sensor included; extras sold separately). Each sensor transmits up to approximately 200 ft/60 m in open areas, so placement across a home or yard is flexible.

• Supports up to three wireless sensors (1 included)
• Transmission range up to 200 ft / 60 m in open space
• Use sensors in baby rooms, sheds, garages, or backyards
• Channel display lets you view each sensor’s readings

How do the alarm and display controls support daily routines?

The SC91 offers two independent alarms with repeat options, a customizable snooze (5–60 minutes), and an auto-off alarm if ignored for two minutes. The large numerical time/date display, adjustable backlight (high/medium/low/off), and 12/24-hour formats make it easy to use at home or bedside.

• Dual alarms with weekday/weekend programming
• Snooze duration adjustable from 5 to 60 minutes or disabled
• Large 4.5" LCD with date, weekday, and trend icons
