## Features

- 6-in-1 Thermo-Hygrometer: This new INKBIRD temperature and humidity detector has a large 3.8-inch LCD screen that clearly displays the current temperature and humidity, comfort level indicators, and the current time and date. Its two display modes, TH mode (mainly by temperature and humidity) and Time mode (mainly by time), are specially designed for different usage needs. You can also check the maximum and minimum values for the past 24 hours/48 hours/ALL times at any time.
- Bluetooth 5.0 Connectivity: The ITH-21-B adopts advanced Bluetooth 5.0 technology, so you can control it with your smartphone and remotely monitor the indoor temperature and humidity changes at an obstacle-free distance of up to 70m/230ft. You can customize the temperature and humidity comfort ranges in the app according to your family's physical quality condition, to confirm whether the indoor temperature and humidity are comfortable or not.
- High Measurement Accuracy: It is equipped with Swiss-made precision sensors from world-renowned Sensirion, which are more accurate, more stable and more reliable. Its temperature measurement accuracy reaches ±0.2°C (±0.36°F) in a wide temperature range of -20°C-60°C (-4°F~140°F) and humidity accuracy reaches ±2% in a humidity range of 0%RH-99%RH, making it a better choice than most temperature and humidity detectors on the market.
- 2-Year History Storage & Export: The device itself can store up to 300 days of offline temperature and humidity data. The exact data capacity varies with the recording intervals, 1min/2min/5min/10min, which can be selected on the INKBIRD app. All data is automatically uploaded to the app via the Bluetooth connection and you can view 2 years of history on the app graph and export the required data to your computer via email for further study of indoor temperature and humidity.
- 15+ Months Battery Life: With the two AA batteries supplied, this indoor temperature and humidity monitor can run for over 15 months at a time. There is no need for repeated recharging or frequent battery replacement, which is more convenient and environmentally friendly. The long battery life makes it suitable for continuous temperature and humidity monitoring in any indoor space such as bedrooms, offices, wine cellars, greenhouses, garages.
