AFIFI AF01-3 Wireless Thermometer Hygrometer 330ft Range Black

Indoor & outdoor climate monitor

The AFIFI AF01-3 wireless thermometer hygrometer tracks indoor temperature from 14.2°F to 122°F and outdoor temperature from -40°F to 158°F with ±0.5°F accuracy. Humidity is measured across a 1%-99% range. A remote sensor transmits data up to 330ft (100m) through walls and updates every 30 seconds. The black display unit measures 2.4in x 3.96in x 1.3in and weighs 0.231kg. It runs on three AAA batteries while the sensor uses two AA batteries, none included.

Replaces standalone indoor thermometers

This unit replaces separate indoor-only thermometers and basic hygrometers that lack outdoor reach or forecast capability. The jump is worth it when you need simultaneous indoor and outdoor readings plus a 12-24 hour weather forecast driven by barometric pressure and humidity trends. It also adds high/low records, a clock, calendar and alarm with snooze in one device. Buyers who only need a single-room temperature check or who require data logging and smartphone alerts will not find those features here.

Check power and mounting before ordering

Verify you can supply three AAA batteries for the main unit and two AA batteries for the included sensor. Decide whether you will wall-mount or stand the display on a flat surface. Confirm the 330ft wireless path between sensor and display is not blocked by dense metal structures that could reduce range. If you plan to monitor more than one outdoor location, note that up to two additional sensors are sold separately.
