Smart sensor with 4.6" display

The Emerson RCD11A is a battery-operated smart sensor featuring a 4.6-inch LED display for clear indoor monitoring. It provides temperature readouts and a full calendar with 12- or 24-hour format options. Adjustable brightness and an automatic night light sensor ensure comfortable viewing in any lighting condition. This portable unit suits users needing a compact tabletop clock with environmental awareness.

Fits tabletop spaces without wiring

Measuring 5.8 by 3.5 by 2.3 inches, the device sits neatly on a bedside table or desk without requiring a mains connection. Three AAA batteries power the clock, alarm, countdown timer and illumination functions. The self-contained design frees up wall outlets and eliminates cable routing. An embedded battery is included to maintain time settings during primary cell changes.

Steady operation through ambient shifts

The auto night light sensor activates the display only when ambient light drops, conserving battery life during daylight hours. Adjustable brightness lets the user set a constant output level that the sensor then modulates, preventing sudden glare at night. Temperature readings update continuously without the spikes seen in brief-sensor cycles. Snooze and alarm functions repeat reliably across successive days.

Questions about this item

How long will the three AAA batteries keep the 4.6" display running before they need replacement?

The clock is powered by three AAA batteries; actual runtime varies with brightness setting and alarm use, so keep fresh cells on hand for uninterrupted operation.

Does the auto night-light sensor make the unit warm or audible after hours of continuous use?

The LED display and sensor draw very little power, so the housing stays cool to the touch and produces no fan or coil noise during all-day operation.

Are the three AAA batteries included in the box, or must I supply them myself?

The package contains the clock unit only; three AAA batteries are required and must be purchased separately.
