Bluetooth Temperature Humidity Sensor - This Bluetooth 5.0 temperature and humidity sensor provides a temperature range of -20°C to 65°C (-4°F to 150°F) and a humidity range of 0% to 100% RH. Monitor temperature and humidity data in real time via the compatible app using Bluetooth connectivity. Wireless monitoring allows for continuous tracking and control. Accurate Bluetooth Sensor - Offers precise measurements with temperature accuracy within ±0.5°C (±1°F) and humidity accuracy within ±5% RH. The sensor updates readings approximately once per second, ensuring reliable and up-to-date data transmission. Multifunctional Bluetooth Thermohygrometer - View minimum and maximum temperature and humidity values through the app. Set custom monitoring thresholds; when readings exceed the defined range, the app will highlight values in red and send a notification. The device records a data point every 10 minutes and supports data export for analysis. Easy Pairing - Press the pairing button to establish a Bluetooth connection automatically. The design supports multiple sensor connections, allowing users to identify and manage individual devices without confusion. Adding additional sensors is simple and efficient. Wide Compatibility - Works with smartphones running Android 4.3 and later or iOS 9.0 and later. The companion app supports connection with up to 100 sensors simultaneously. Bluetooth signal range is up to 30 meters (approx. 98 feet) in open space without obstacles.
