High-Precision Sensor - built-in upgraded MEMS sensor, it updates once per second to provide more current data with higher accuracy. The temperature error can be up to 0.5(1℉), humidity error can be up to 5%. With 5.0 Bluetooth chip, the temperature sensor provides wireless real-time monitoring of temperature (-20-60℃) and humidity (0-100RH). Upgraded to 50m(164ft) connection distance (in open area).
Wireless APP Control - the temperature sensor will upload data to the app when connecting via Bluetooth. You can check the maximum and minimum values of temperature and humidity on the app. One smart device can connect to up to 100 temperature sensors at the same time, and supports Android 4.3 or above, iPhone 4s or above.
Smart Alert Reminder - Data in the app will turn red and send a notification to your mobile phone to remind you and your family of temperature and humidity variations when data exceeds your preset value. It can be used to monitor home, pets, refrigerators, freezers, walk-in coolers, wine cellars and greenhouses.
Data Storage Export - Wireless thermometer hygrometer records data every 10 seconds in the app, which is totally up to 100 days. (make sure your phone is within range of it at least once a day.) Able to download data in CSV format for free after registered account.
Mini Portable Design - Our wireless temperature and humidity sensor is smaller than others (1.5 x 1.5 x 0.62 inch) and has a built-in CR2477 battery, it weighs about 37 grams per piece. The battery life is about 10 months. A hanging hole is designed for different placements as you like. Space-saving and convenient.
