SMARTRO SC91 Projection Alarm Clock — Red Projection, Weather Station, Dual Alarms & Remote Sensor

The SMARTRO SC91 is a bedside projection alarm clock that displays time, indoor/outdoor temperature, humidity and short-term weather forecasts while projecting time or temperature onto your ceiling or wall.

Compact and feature-rich, the SC91 combines a 4.5" backlit LCD weather display, a red projection lamp with adjustable angle and brightness, and a wireless remote sensor for outdoor or remote indoor readings. It’s designed for bedrooms, nurseries, and living spaces where you want quick, at-a-glance environmental data and an easy-to-read projected time. The unit supports dual alarms, snooze, 12/24-hour formats, and can accept up to three remote sensors for multi-zone monitoring.

How does the projection feature help at night?

The soft red projection makes the time or temperature visible across the room without turning on a bright display. You can tilt and reverse the projector 180 degrees to aim the readout at your ceiling or wall and adjust brightness for comfort.

• Projects time or temperature in soft red for low-light viewing
• Adjustable angle and 180° reversible projection
• Multiple brightness levels to reduce night glare

What environmental data does the SC91 provide?

The SC91 shows indoor and outdoor temperature and humidity on its large LCD and indicates short-term weather trends using barometric pressure and icons. It also alerts to mold risk and displays temperature trends so you can quickly see whether conditions are changing.

• Indoor and remote (outdoor) temperature and humidity readings
• Weather prediction for the next 12 hours and pressure trend
• Mold risk indicator and clear weather icons on a 4.5" screen

Can I use multiple sensors and how far do they reach?

The base station accepts up to three wireless remote sensors (only one included; extras sold separately) so you can monitor several rooms or an outdoor location. Each sensor transmits up to about 200 ft/60 m in open air, making it suitable for homes, yards, garages or nurseries.

• Supports up to three wireless remote sensors (1 sensor included)
• Sensor transmission range up to 200 ft/60 m in open area
• Place sensors in baby rooms, storage areas, or outdoors for multi-zone readings

How do the alarm and display options improve daily use?

The SC91 offers two separate alarms with weekday/weekend scheduling and an adjustable snooze from 5 to 60 minutes. The large numeric time, selectable 12/24-hour formats, date, and weekday make the display easy to read, and the backlight dimmer gives four brightness levels for day or night.

• Dual alarms with independent settings and weekday/weekend repeat
• Snooze adjustable from 5 to 60 minutes or disable snooze
• Adjustable backlight (high, medium, low, off) and clear large digits

Who is this for: The SMARTRO SC91 is aimed at people who want a multifunction bedside weather clock that delivers easy-to-read environmental data and projection without being reliant on atomic signals. It’s well suited for parents monitoring a nursery, homeowners tracking indoor comfort and mold risk, or anyone who prefers a projected time display and multiple-zone temperature monitoring. If you need multiple sensors, plan to purchase additional SMARTRO remote units to expand coverage.
