Wireless Indoor and Outdoor Thermometer

Compare indoor and outdoor temperature from one display with a wireless thermometer that keeps minimum and maximum records.

✅ Read two locations from indoors - The wireless outdoor sensor sends readings to the main temperature display.

✅ Review the extremes between checks - Minimum and maximum records show more than the current reading.

✅ Choose a convenient display position - Standing and wall-hanging arrangements support different room layouts.

✅ Use familiar temperature units - Celsius and Fahrenheit selections let you choose the format you prefer.

Follow the change as well as the current temperature

An outdoor reading is useful when you can check it without stepping outside, while the indoor value provides a comparison. Put the outdoor sensor in an appropriate representative position and allow it to settle before judging the readings.

The stated 100 m wireless range is for open space, so walls and placement affect actual reception. Test the intended locations and use suitable batteries, especially where the outdoor sensor will experience cold conditions.
