Senior-Friendly 3.8" Display

This wireless thermometer hygrometer features a 3.8-inch LCD with large digits and a clean layout designed for older adults. The screen shows indoor temperature and humidity alongside outdoor readings from up to three remote zones. One outdoor sensor is included in the box and the main unit can be placed on a tabletop or wall-mounted for convenient viewing.

Upgrade from Single-Zone Units

If you currently rely on a basic indoor-only thermometer or a single-sensor model this unit adds simultaneous monitoring of three outdoor locations such as a garden greenhouse or basement. The jump is worth it when you need to track temperature differences across separate areas without buying multiple standalone devices. The integrated alarm clock with a five-minute snooze and a ten-second blue backlight also replaces a separate bedside clock.

Check Sensor Placement and Power

Verify that the outdoor sensor can be positioned within wireless range of the main unit and that the mounting location stays within the operating range of 14.2 to 122 degrees Fahrenheit. The device runs on two AA batteries which are not included so have them ready for installation. Ensure the display size of 3.8 inches fits your intended surface whether it is a nightstand kitchen counter or wall.
