With the built-in MEMS sensor, the cooler thermometer gives you high-precision monitoring. Temperature deviation: ± 0.5°C (± 1°F); Humidity deviation: ± 3% RH.

The data is automatically updated once per second. Connection range up to 20 m (without obstacles).

The temperature sensor uploads the data to the app when it connects to the APP via Bluetooth. You can set the monitoring range. The data on the app will be displayed in red if it is outside the set range.

The sensor uses a high-end Bluetooth 5.0 chip.

Temperature Range: -20-60°C (-4-140°F) Humidity Range: 0-99% RH. Smaller size: (1.3 x 1.3 x 0.47) inches.

A hanging hole is provided for different attachments, depending on what you want.

Every 10 minutes and up to 100 days, total data is stored internally in the device. Please make sure your phone is within range at least once a day.
On some models with buzzer alarm, the alarm will be displayed on the device when the temperature or humidity is out of range.

It's not a radiator thermometer, please don't put it in the fridge!!!
