Easily monitor temperature and humidity data in the Blue sensor via Bluetooth. Wireless real-time monitoring keeps everything under control.Accurate Bluetooth Sensor With the Bluetooth sensor, it offers more accurate monitoring. The temperature is accurate within 0.5 ( 1 ) and the humidity is 5% RH. The Bluetooth thermohygrometer is basically updated once per second so that the measurement is more accurate.Multifunctional Bluetooth Thermometer You can display the minimum and maximum temperature and humidity by connecting to the app via Bluetooth. You can also set the monitoring range for temperature and humidity. The value in the app will turn red when it is out of the monitoring area and send you a reminder.

If you need to connect multiple sensors to an app, the pairing button allows you to understand the appropriate Bluetooth hygrometer clearly without creating confusion. Adding Bluetooth sensors is handy.Wide Compatibility The Bluetooth temperature sensor supports Android 4.3 and above/iOS 4s and above mobile phones that can be used with wide compatibility. Smart Bluetooth app can connect up to 100 at the same time. When the mobile phone receives data from the thermometer, the distance to the sensor without obstacles should be a maximum of 30 meters.
