= '''<big>Definition and purpose of the sensor</big>''' =

The TH-BLE humidity and temperature meter (hereinafter referred to as the meter, product, sensor, TH-BLE) is designed to measure the temperature and humidity of the external environment.  

The TH-BLE sensor reads air temperature and humidity values in the immediate vicinity of the measuring probe, estimates the remaining capacity of batteries; transmits the received measurement values via wireless communication channel to a tracker with BLE interface, a mobile device equipped with BLE interface or a BLE-BASE signal receiver. Depending on the version TH-BLE can also additionally measure illumination, determine the presence of magnetic field by hall sensor and monitor the state of two binary inputs (for limit switches).

Launch the app and activate '''Bluetooth''' and geolocation on your smartphone also check if application have access to '''geolocation'''.

== '''<big>Connecting sensor</big>''' ==

Press the '''Sensor Settings''' button. Next, select '''TH-BLE'''.

Find the required sensor by typing the last 6 digits of its serial number. You can find the serial number on the sensor head.

You can also simply select the required sensor from the list and click the Connect button. On an Android device, you can click on the sensors name, and a package of data received in advertising mode will be displayed.

== '''<big>Setting a password</big>''' ==

You can set, change and delete a password in the '''Settings'''.

Then, in the field that appears named "Password for changing settings", enter the password that you want be used later and click '''Enter'''.

<blockquote>'''<big><u>PLEASE NOTE THAT THE PASSWORD RESET PROCEDURE CAN BE VERY TIME-CONSUMING. WE RECOMMEND THAT YOU TAKE A RESPONSIBLE APPROACH IN SETTING YOUR PASSWORD AND SAVING IT.</u></big>'''</blockquote>'''<big>Also note that the password cannot start with 0.</big>'''

'''The battery voltage drops to 3.2V for 10-15 seconds''' - this is normal (especially if this happens after rebooting the sensor by removing the sensor battery and then installing the battery back). This is due to the fact that all processes in the sensor (measuring level, temperature and battery voltage, as well as sending a data packet) are launched simultaneously, thus energy consumption increases, which leads to a temporary decrease in battery voltage.

You can also synchronize the time manually by going to the '''Settings''' '''menu(1''') and clicking '''Synchronize time(2''').

Then, click on the '''Save data button''' ('''1'''). A graph will appear on the screen. On the graph screen, you can also save the upload file to your phone’s memory ('''2''') or send it via instant messengers or email ('''3''').

Also, graphs from the black box can be viewed on a PC using a calibration table through the [https://docs.google.com/document/d/1CdFPhy2SVu3DxVLy4tY0j1YlaVjdB3ykyLR21iuAwYs/edit?usp=drive_link Escort Charter]

If you have previously saved data from the black box, you can '''display''' it by clicking on the '''graph icon''' in the upper right corner ('''1''')
