Indoor and outdoor monitoring

This wireless thermometer measures temperature inside and outside the home, displaying readings in Fahrenheit. It is suited for homeowners who want to check HVAC coverage, spot drafts or keep an eye on conditions in a garage or greenhouse. The compact display fits on a tabletop or mounts on a wall for at-a-glance viewing. It is not for users who need data logging, high/low alerts or smart-home integration.

Range and update rate

The outdoor sensor transmits to the display from up to 100 feet (33 meters) away using an enhanced 433 MHz signal that penetrates walls well. Readings refresh every 60 seconds, giving near real-time feedback on temperature changes. The sensor’s precision thermistor is rated down to -40 degrees, so it continues reporting in hard freezes. Buyers who need multiple sensors or longer range will find this single-channel unit limiting.

Power and quiet operation

Both the display and the sensor run on batteries with no cords or fans, so the unit adds no audible noise to a room. Typical battery life spans many months under normal use, keeping maintenance low. The simple LCD draws very little current, and there are no backlight or radio features that would increase draw. Users who prefer mains-powered or rechargeable designs should look elsewhere.

Questions about this item

Will the 433 MHz sensor still transmit through the thick stone wall of my older house?

The enhanced 433 MHz signal penetrates walls up to 100 feet (33 meters) away, so a stone wall within that range should not block the 60-second updates.

How can I verify the outdoor sensor is reporting correctly down to minus 40 degrees after I mount it?

Compare the display reading with a known thermometer at the sensor location; the precision thermistor is rated to -40 °F and updates every 60 seconds.

Does the package include mounting hardware for the keyholes on both the display and the sensor?

The box contains the display unit, wireless sensor and batteries; screws or anchors for the integrated keyholes are not included and must be purchased separately.
