## Description

Product Description INKBIRD ITH-21-B Bluetooth Smart Thermo-Hygrometer The new INKBIRD intelligent temperature and humidity detector is equipped with an industrial-grade sensor manufactured by Sensirion, a company based in Switzerland. The sensor is capable of achieving a great deal of accuracy in both temperature and humidity measurements, with an error margin of ±0.2℃ and ±2%, respectively. The device's distinctive design incorporates both date and clock functions, with a large 3.8-inch screen that facilitates clear and straightforward visual interpretation. Wide Range of Applications

Review: Got what I wanted. Great product - This is exactly the product I wanted. This watch is powered by two AA batteries and not usb charged which would have been better though. But I got few features with this, switchable time / temp.& humidity. It is quite accurate. Wanted a clock that could connect with phone to regularly update the time delay which happens to anlalog or independent digital watch, so it syncs with gps time of phone just by connecting to the app. Plus it also shows pressure and dew point in the app with trends of day/week/month/year which is quite accurate. Gives you comfort levels of temp. and humidity which you can also set according to your choice. Lastly the price is quite reasonable as you get very less features at this price. Quality is great, easy to use , compact size and great functionality. What else is required.
Review: Good product - Worth of money good product 99% accuracy and build quality also good

## Features

- 6-in-1 Thermo-Hygrometer: This new INKBIRD temperature and humidity detector has a large 3.8-inch LCD screen that 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, ensuring a healthy and safe living environment for your family.
- 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: 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, helping you to maintain an optimal environment for your family, pets or delicate objects.

*by P***B on 8 January 2026*

pretty accurate slightly expensive i have another tapo smart hygrometer the temperature readings are almost equal but the indoor humidity shown by inkbird is 3-5 % less than that shown by tapo. i think this is more accurate but since it works on aa batteries with no usb also no backlight i have given 4 stars
