4-Pack Indoor Climate Sensors

This 4-pack supplies four compact sensors for monitoring temperature and humidity inside the home. Each unit connects directly to a 2.4 GHz Wi-Fi network without a separate hub. The sensors feed data to the Tuya Smart or Smart Life app, making them suited to anyone who wants multi-room visibility from a single phone.

Temperature -20 to 60 °C Humidity 0 to 100 % RH

The sensors measure temperature from -20 to 60 °C with ±1 °C accuracy and humidity from 0 to 100 % RH with ±5 % RH accuracy. Free app storage lets you view history records and graphs over time. Accuracy drops if a unit sits near a heat source or inside an enclosed space, so placement matters for reliable readings.

Compact Plastic Build Multiple Mounting Options

Each sensor measures 2.72 in x 0.96 in x 0.76 in and weighs 196.8 g including two included AAA batteries. The ABS plastic body can rest on a shelf, stick via the supplied adhesive, or be screwed to a wall. The small footprint fits potted plants, vivariums, humidors and similar tight spaces.

Questions about this item

Will the 2.4 GHz Wi-Fi sensor work on my existing 5 GHz network?

The sensor only connects to 2.4 GHz Wi-Fi (802.11b/g/n); it will not join a 5 GHz network, so your router must broadcast a 2.4 GHz SSID for setup.

How can I verify the TH01 is reporting correctly after pairing?

Open the Tuya Smart or Smart Life app and check that live readings fall within -20 to 60 °C and 0 to 100 % RH with the stated ±1 °C and ±5 % RH accuracy.

What comes in the 4-pack box and what must I buy separately?

The box includes four TH01 sensors and eight AAA batteries (two per unit); no hub is required and no extra accessories are needed for basic operation.
