Bluetooth Temperature and Humidity Sensor - The Bluetooth 5.0 temperature sensor provides you with a temperature range of -20 ~ 65 ℃ (-4 ~ 150 ℉) and a humidity range of 0% RH. 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, more accurate monitoring is offered. The temperature is accurate within ±0.5 ℃ (±1 ℉) and the humidity is ±5% RH. The Bluetooth thermo-hygrometer basically updates once per second so that the measurement is more accurate. Multifunctional Bluetooth Thermometer You can view 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 turns red when it is outside the monitoring range and sends you a reminder. The thermometer records a data set every 10 minutes and also supports exporting temperature data. Just pair the device After pressing the pairing button on the Bluetooth thermometer, it connects automatically. If you need to connect multiple sensors to an app, the pairing button allows you to clearly understand the appropriate Bluetooth hygrometer without creating confusion. Adding Bluetooth sensors is practical. Wide Compatibility The Bluetooth temperature sensor supports Android 4.3 and later/iOS 4s and later mobile phones that can be used with wide compatibility. The smart Bluetooth app can connect up to 100 simultaneously. When the mobile phone receives data from the thermometer, the distance to the sensor without obstacles should be a maximum of 30 meters.
