Wireless thermometer hygrometer, Bluetooth thermometer hygrometer with app and data storage, digital temperature and humidity sensor for home, office, greenhouse, cellar

Bluetooth Wireless Connection: The temperature and humidity sensor uses a high-end Bluetooth 5.0 chip. It provides real-time wireless monitoring of temperature from -20 to 65°C (-4 to 150°F) and humidity (0 to 100% RH). Temperature and humidity data can be easily monitored remotely via Bluetooth in the app, allowing multiple devices to be connected simultaneously.

Superior Accuracy: Thanks to its precise and sensitive temperature and humidity sensor, the Bluetooth thermometer can detect a temperature error of ±0.5°C (±1°F) and a humidity error of ±5% and can be updated once per second for greater accuracy.

Precise measurements allow you to make timely adjustments in your basement, greenhouse, or elsewhere.

【Free Data Storage and Export】 Supports temperature data export, recording a data set every 10 minutes, and can store up to 100 days of data backup. After creating an account, the data in CSV format can be downloaded for free.

Smart App with Notifications: After a successful Bluetooth connection, the mini Bluetooth sensor uploads data to the app. You can view the maximum and minimum temperature and humidity values via the mobile app. You can also set the temperature and humidity monitoring range. Notifications are immediately sent to the app if the data falls outside the preset range.

Compact Mini Size: Our wireless thermo-hygrometer has a smaller and more compact design (1.5 x 1.5 x 0.62 inches), making it lightweight and easy to carry. A hanging hole is provided for various placements according to your preferences. The CR2477 battery has a lifespan of approximately 1 year and can be replaced by the user.
