**High-precision sensor:** Built-in upgraded sensor updates every second for faster data. The temperature error is ±0.5°C (±1°F), humidity error is ±5%. Uses a Bluetooth 5.0 chip for wireless real-time monitoring of temperature (-20-60°C) and humidity (0-100% relative humidity).

**Wireless app control:** The temperature sensor uploads data when connected to the app via Bluetooth. You can view maximum and minimum temperature and humidity values in the app. Up to 100 temperature sensors can be connected simultaneously to smart devices.

**Smart alerts:** Data in the app turns red and sends a message to your phone, reminding you and your family to pay attention to temperature and humidity changes when data exceeds preset values. It can be used for monitoring in homes, for pets, refrigerators, freezers, clothes coolers, wine cellars, and greenhouses.

**Data export and storage:** The wireless thermometer and hygrometer record data in the app every 10 seconds, for a total of up to 100 days. Make sure your phone is near the sensor at least once a day. Register an account to download CSV data for free.

【Mini and portable design】—Our wireless temperature and humidity sensor is smaller than other products (1.5 x 1.5 x 0.62 inches). Battery life is approximately ten months. The hanging hole allows for customized placement according to your preferences. Space-saving and practical.
