3 How to use

    1.After installed 2pcs batteries, the device starts. The LCD displays the current temperature and humidity data, and the data update cycle is 30 seconds. Simultaneously send out BLE broadcast and last for 3 minutes. At this time, signal sign on the LCD screen (indicated by the arrow in Figure 1-1) flashes, and the device can be found and connected by the mobile phone. If there is no mobile phone connect it after timeout, the BLE broadcast will turned off, and the LCD signal sign disappears. Shortly press the button (indicated by the arrow in Figure 1-2) to re send the broadcast
